I dont think he's squeezin light because of the presence of uber-donk (63vpip) & you raised UTG+1.
Im sure he expects donk at least to call and overplay his hand post-flp.

I think pkt4's is spot-on but with the large 3bet size, u raising utg+1 & not closing the action, (donk 80bb will sometimes shove his 66 etc here, bb will call & you be out your 10$) , I think a fold is probably best.

... Not that I'll ever fold here
