(PCA Step 3) AJ, bizarre villain line

[sapsuckah]

First level so no solid reads, but villain gives off a donkish vibe... has limped a couple times pf already and has already made two preflop minraises.

Pretty sure this is a way easy fold but can anyone interpret what this clown is doing?

Comments on flop action? I was planning to check-call, but I switched it up after his minbet.
