Huh? Limp Reraise, from the third limper

[Wideout88]

Villain's numbers are 12/4 PAF 8.00 and WTSD 5% over 112 hands

This is my first hand at the table, I have $100 he has me covered.

Preflop: Hero is SB with J[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/heart.gif[/img].
UTG Calls $1, UTG+1 Calls $1, MP1 Calls $1, 3 Folds, Hero raises to $6, 2 folds, MP1 reraises to $20, Hero...

Ok what does that mean? He limped third, what kind of range should I put him on? Is he getting real tricky with AA, KK, or is this some weird resteal with position and 33-99 or Axs. So anyway he confused me, so I let my time bar run and called him, which I think is a big mistake considering im out of position. Do you fold here, or reraise him back?
