Overcards: Misplaced Aggression or a Good Semi-Bluff?

[Moneyline]

Wacky Party 5/10 game 10 handed

UTG folds, EP (loose/passive) & EP2 (clueless magoo) call, 2 folds, I raise K [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/diamond.gif[/img] from LMP, button (loose/passive) cold calls, folded to EP who calls, EP2 calls.

Flop: T [img]/images/graemlins/heart.gif[/img] 4 [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/heart.gif[/img] (4 players, 9 SBs)

EP checks, EP2 bets, I raise, button cold calls, EP cold calls, EP2 3bets, everyone calls.

Turn: J [img]/images/graemlins/spade.gif[/img] (4 players, 10.5 BBs)

EP checks, EP2 bets, I call, button raises, EP cold calls, EP2 calls, I call.

River: 6 [img]/images/graemlins/club.gif[/img] (4 players, 18.5 BBs)

Checked to the raiser who bets, SB folds, EP2 calls, I fold.

So how about the flop raise? Is this a good spot to try to clean up some outs, or am I misapplying the concept?
