Hero: $27

Villain: $30

I was playing 10/25c ring game. I was big blind with average stack of $27. It was folded around to the button($30), who raised to 75c. SB folded and I 3 bet to $2.50.  The button re-raised to $5.20. I only just joined the table a few hands before and had no reads or experiences with the other player. I flat called.

The flop: 7x 2x 3x Rainbow.
I check to the button and he goes all in putting me at risk. After taking my time to think about it, I fold. 

Any thoughts?
