köken: From the onomatopoeic interjection bums, bum + -sen (iterative suffix). The sexual sense rose to prominence in the mid of the twentieth century, when before rumsen was used the same way, now not known any more.
köken: Inherited from Middle French baiser, from Old French baisier, from Latin bāsiāre (“to kiss”). As far as the verb is concerned, the meaning “fuck” arose via euphemism and has become the dominant sense.
köken: From French explosion, from Latin explōsiōnis, genitive form of explōsio, from explōdo (“to drive out by clapping”), from ex- and plōdo (“to clap or strike”).
köken: Inherited from Old Galician-Portuguese comer, from Vulgar Latin *comēre, restructuring of Latin comedere. Cognate with Galician, Mirandese, Asturian, and Spanish comer and Mirandese quemer.
