5.50 Called PF push w/A-Q offsuit

NO_LIMIT TEXAS_HOLDEM $5+$1 (real money)

SB=$10 BB=$20
Villain is SB
Hero is in the BB

This is not a play I would normally make, but the Villain in this case had already revealed himself to be quite the donkey. I had also observed two previous cases of the button pushing w/multiple limpers.

Is this ridiculous? I actually felt quite good about it, given my read. I figured this guy had seen a similar play work twice before and was pushing w/any two paint. I also figured him for the type that would incorrectly slow play a monster PF.

Too loose? And if so, what's your calling range given my read?
