bonkers (adj.): "crazy," 1957, British slang, perhaps from earlier naval slang meaning "slightly drunk" (1948), from notion of a thump ("bonk") on the head.
bonnet (n.): late 14c., Scottish bonat "brimless hat for men," from Old French bonet, short for chapel de bonet, from bonet (12c., Modern French bonnet) "kind of cloth used as a headdress," from Medieval Latin bonitum "material for hats," perhaps a shortening of Late Latin abonnis "a kind of cap" (7c.), which is perhaps from a Germanic source.
bonny (adj.): 1540s, of unknown origin, apparently from Old French bon, bone "good" (see bon).
bonnyclabber (n.): 1620s (in shortened form clabber), from Modern Irish bainne "milk" (from Middle Irish banne "drop," also, rarely, "milk"; cognate with Sanskrit bindu- "drop") + claba "thick." Compare Irish and Gaelic clabar "mud," which sometimes has made its way into English (Yeats, etc.).

boo: expression meant to startle, early 15c., boh, "A combination of consonant and vowel especially fitted to produce a loud and startling sound" [OED, which compares Latin boare, Greek boaein "to cry aloud, roar, shout."]; as an expression of disapproval, 1801 (n.), 1816 (v.); hence, the verb meaning "shower someone with boos" (1893).

Booing was common late 19c. among London theater audiences and at British political events; In Italy, Parma opera-goers were notorious boo-birds, but the custom seems to have been little-known in America till c. 1910.

To say boo "open one's mouth, speak," originally was to say boo to a goose.
To be able to say Bo! to a goose is to be not quite destitute of courage, to have an inkling of spirit, and was probably in the first instance used of children. A little boy who comes across some geese suddenly will find himself hissed at immediately, and a great demonstration of defiance made by them, but if he can pluck up heart to cry 'bo!' loudly and advance upon them, they will retire defeated. The word 'bo' is clearly selected for the sake of the explosiveness of its first letter and the openness and loudness of its vowel. [Walter W. Skeat, "Cry Bo to a Goose, "Notes and Queries," 4th series vi Sept. 10, 1870]
boo-boo (n.): "mistake," 1954, apparently a reduplication of boob, which had acquired a secondary sense of "foolish mistake" (1934).

boo-ya: also booyah, exclamation used in various situations, first attested c. 1990 in hip-hop slang.
boob (n.): "stupid person," 1909, American English slang, perhaps from booby.
boob tube (n.): "television set," U.S. slang, by 1965, from boob "stupid person" + slang tube (n.) "television, television programming," because the sets really did have vacuum tubes in them once upon a time.
boobs (n.): "breasts," 1929, U.S. slang, probably from much older term boobies (late 17c.), related to 17c. bubby; perhaps ultimately from Latin puppa, literally "little girl," hence, in child-talk, "breast." Or else it is a natural formation in English (compare French poupe "teat," German dialectal Bubbi, etc.).
booby (n.): 1590s, from Spanish bobo "stupid person, slow bird" (used of various ungainly seabirds), probably from Latin balbus "stammering," from an imitative root (see barbarian).

Booby prize is by 1883: an object of little value given to the loser of a game; booby trap is 1850, originally a schoolboy prank; the more lethal sense developed during World War I.
At the end of every session the dominie had the satirical custom of presenting his tawse as a "booby-prize" to some idle or stupid lout whom he picked out as meriting this distinction so that next time they met he might start fresh and fair with new pair for a new set of classes. [Ascott R. Hope, "Dumps," "Young England" magazine, 1883]
boodle (n.): 1833, "crowd;" 1858, "phony money," especially "graft money," actual or potential (1883), both American English slang, either or both based on bundle, or from Dutch boedel "property."

boogie (v.): originally "dance to boogie music," a late 1960s style of rock music based on blues chords, from earlier boogie, a style of blues (1941, also as a verb), short for boogie-woogie (1928), a reduplication of boogie (1917), which meant "rent party" in American English slang. A song title, "That Syncopated Boogie-boo," appears in a copyright listing from 1912.
book (n.): Old English boc "book, writing, written document," traditionally from Proto-Germanic *bokiz "beech" (cognates: German Buch "book" Buche "beech;" see beech), the notion being of beechwood tablets on which runes were inscribed, but it may be from the tree itself (people still carve initials in them). The Old English word originally meant any written document. Latin and Sanskrit also have words for "writing" that are based on tree names ("birch" and "ash," respectively). Meaning "libretto of an opera" is from 1768. A betting book is from 1856.
