QQ OOP in reraised pot

Clearing the bonus at the Party $50 tables...Villian here is 17.5/2.9/1.3 just after 150 hands with him. $50 effective stacks.

UTG+1 minraises, a call, villian calls in the cutoff, button calls, i reraise to $6 from the sb, bb folds, and it folds to villian who calls, button drops as well.

Flop is J 6 3 rainbow
I lead for $12 into a $15.xx pot and he pushes, I get really confused.

I call this.

I go into shock and recover when my timer has run out
