Origins unknown; used as a codeword to describe people hooking up; now used as common slang in (mostly the north of) Scotland to describe any kind of sexual activity, and indeed many other activities which have little or nothing to do with sex, and is generally used to indicate that something fortunate has occurred. It can be used as a legitimate verb in regular conversation, but it is normally just shouted, and is accompanied by a hand action where one puts the thumb and middle finger together, and taps them with the index finger.

Another word for 'lady parts' (the vagina).
So I met this 27 year old dentist, who drives a BMW, and I took him back to my place where he was all up in my sweesh, but I was like dude I can't, so then we didn't do anything involving my sweesh.
