Spew with AA?

[lastcardcharlie]

Can't remember the exact details and no reads, but ..

Pokerroom .15/.25, five-handed. Hero in SB with AA, Villain in BB, both have about $25.

Pre-flop: UTG and CO limp, Button folds, Hero raises to $1, BB, UTG and CO all call.

Flop: 882 r

UTG checks, CO checks, Hero bets $2.5, BB bets $10, UTG, CO both fold and ... Hero shoves.

Limit instincts affecting my game. In the absence of a good read this is terrible, terrible spew, right?
