slang word reffering to sex, which must be used in physics lessons when you are surrounded by pre-pubescent little boys to decribe to your girly buddies what happened last night, with you and your gorgoes bloke. Kascrew, Kaboom and Kabamm also work well
''Hey did you do the big kaboosh last night?'' ''I sure as hell did''
