Any inane girl/guy (mainly girls) who think that pashing their best friend/another chick in a pub/club in order to give the impression that they are bi-sexual - is cool. Usually done to titillate a boyfriend or male onlooker with no intention or desire to follow through with same-sex actions. Pseudo-sexual behaviour of the lowest order. Should be exposed for the sexual fraud it is.
Usually localised to a bar or the like and same 2 chicks would never kiss elsewhere.

"look at that guy over there, do you think he will notice if we pash?"
