a fold ive never seen before

[vkotlyar]

15-30 game. I fold my hand UTG. My friend opens next w AKo. A loose, gambling player cold calls. Mr. Fishy cold calls. A very inexperienced, tight, unimaginitive palyer 3 bets in MP. A very TIGHT player calls 3 bets cold in the CO. The BB calls. The gambling player has 6 chips in his hand, ready to cap. My friend shrugs, and folds.
Can this possibly be correct? I think i might fold AQo here, and def fold AJo, but can any1 justify this fold?
thanks for all the replies
