NL200 - Why is he shoving trips here if he has it?

NL200 FR

Villain has $217, I have $200

When he's raised preflop, it's usually been at least 5x and upwards of 9x, and then he'd proceed to pot the flop then move AI on the turn regardless of how many people were in the pot or how big the overbet was. He hasn't been called, and I haven't seen him play any other pots besides those situations and when he's called a pfr then check/folded flop.

6 folds, Hero raises to $7 with A[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/heart.gif[/img], Villain calls, BB calls.

Villain goes all-in for $201, Hero fist-pumps?
