50 NL - Villain pushes my bottom 2 pair on the turn

[thing85]

Villain is unknown, I just sat down.

I often limp after a min-raise with SCs like this on the button when there are a lot of people in the pot. I know most people prefer to raise or fold, but I will (not often, however) play this kind of hand this way PF.

Does villain do this with anything less than 2 pair (one that beats mine)? I'm getting a little over 2:1 to call with 4 outs to improve. UTG did min-raise PF, so I'm thinking it could he likely has either a large PP (AA or KK) or decided that to randomly donk min-raise PF. Can I find a fold here or should I call?
