Usually "out on the lam" A night of intense, usually unplanned partying and/or bar-hopping involving excessive alcohol consumption, inadequate food, somewhat-manic laughter and random escapades. Most often, but not exclusively, used to describe female-only nights out. The archetypal night on the lam: a hen night.

A word one would use as an excuse to complement or comment on the front logo of a t-shirt of a female if he (or she) is caught looking or staring at her boobs.
Also people could say that to accuse others for blaming them for looking at their boobs when they were looking at the boobs or were not looking at the boobs.
Other words may be El Aye Em, Lammin', or Fuckin' Lamz.
