Totally lost TPWK - weird hand

[TheWorstPlayer]

No reads - I'm new to the table and have never played with any of these guys before. That's what I get for not playing poker for two weeks. For some reason I felt like a deer trapped in the headlights on this hand. It was something about his bet sizes or something. What do you guys think?
