25NL, stupid or ballsy raise with TPTK?

[doublehawk]

Villain was 54/16/3.5 (after only 40 hands or so), and had donked into me and others a couple of times while i'd been there. Looking back on it though, i'm not so confident about my play - I really had to be behind. Was it an acceptable bluff, or kinda idiotic?
