bog
n. countablen. a soft, wet area of land that is often covered with grass and water. You can sink into it if you walk on it.
n. an area of wet, spongy ground that has accumulated peat and is often waterlogged.

The ancient bog preserved the wooden remains of a prehistoric settlement.
Inherited from Middle English bog (originally chiefly in Ireland and Scotland), from Irish and Scottish Gaelic bogach (“soft, boggy ground”), from Old Irish bog (“soft”), from Proto-Celtic buggos (“soft, tender”) + Old Irish -ach, from Proto-Celtic -ākos. The frequent use to form compounds regarding the animals and plants in such areas mimics Irish compositions such as bog-luachair (“bulrush, bogrush”). Its use for toilets is now often derived from the resemblance of latrines and outhouse cesspools to bogholes, but the noun sense appears to be a clipped form of boghouse (“outhouse, privy”), which derived (possibly via boggard) from the verb to bog, still used in Australian English. The derivation and its connection to other senses of "bog" remains uncertain, however, owing to an extreme lack of early citations due to its perceived vulgarity.

Uncertain, although possibly related to bug in its original senses of "big" and "puffed up".
From bug off, a clipping of bugger off, likely under the influence of bog (coarse British slang for "toilet[s]").
From an abbreviation of Bogdanoff, in reference to Igor and Grichka Bogdanoff.
