Pulling an MJ

The act of claiming to have no cash for social activities then going on to buy numerous expensive items.

Person A: I thought you said you had no money for nights out yet you’ve been to three festivals this year bought a brand new car and 3 new sets of clothes?

Person B: Sorry I actually had money this whole time I just didn’t want to spend it.

Person A: You’ve been pulling an MJ on us this whole time!!!
