pull a Zewald

To pretend you have to leave early just to get rid of annoying person in the pub. Upon leaving the pub, make sure all your friends go in one direction and the annoying person in the other. When he/she is out of sight, it's safe to go back in a have a good time with your friends!

Man, who invited X, we had to pull a Zewald on the annoying bastard!
Good fun after he left though.
