Irish Rover 

(v.) When John Mayer takes a dump on your chest.

John Mayer is so hot. I would totally let him Irish Rover me.

reverse irish leave 

An announcement of leaving only to linger longer.

John was annoyed that Jane stayed so long at his party after disrupting the guests with overly dramatic, attention-starved antics like hugging, high-fives and other reverse irish leave moves.

Reverse Irish Buck 

A buck who on his big night out says he is not going to drink much and will have an early night, whereas, in reality the reverse happens.

Igor is getting married so we took him out for his Bucks' party, we all thought it was going to be a quiet one until the drinking began. Never thought he would turn out to be a Reverse Irish Buck, he was soo drunk he passed out on the way to the wedding.
