Sesh Snake

A so called “friend” who says that they cannot come out and “sesh”, yet proceeds to go out anyway, (most likely with a different group of friends). This behaviour is “snakey” and therefore the perpetrator is known as a “sesh snake”.

“Will is a right sesh snake! He said he wasn’t going to go out yet he woke up with sick in his sink and had no memory of his night.
