Misplayed on every street?

[private joker]

I've been having nightmares about this hand since Friday. You guys can create a poll if you want to debate which street is more horrific.

Backdrop: I'd just had a rush of premium starting hands, so I'd been raising a lot PF, which, in a game like the Commerce 20, calls attention to itself.

So I get 88 UTG and open-limp this time. Pots have been super-multiway, so I wasn't too worried.

Of course it gets folded to MP2 who raises, button cold-calls, BB calls.

Flop is 655. Checked to me and I donk. MP2 raises, button folds, BB cold-calls. (Quick reads: both are total unknowns; weekend tourists I've never seen before, been playing with them less than 30 minutes). I call.

Turn is 9. BB now donks. I call. MP2 calls.

River is a 4. BB now checks. I check. MP2 quickly bets, BB quickly calls... so I fold.
