Hand v Sethypooh and a Lagdonk/maniac

[Tryptamean]

SB=Sethy
BB= this 60/50/3.5 dude over 80 hands, but seems to be more spewy pf than post flop, and has also been hitting some hands here and there.

What is the best course of action? I suppose folding preflop should probably be default.... IF that's the case, just assume I was suited in spade or something, because I'm kind of interested in seeing what the best action is
