Question about a hand

Home game. Tournament was on the bubble. I was in the BB with only one chip remaining and a garbage hand. Under the gun raised and the loose/aggressive button went all in. SB folded. I paused, sensing the UTG loose/aggressive would call, so I folded, hoping the UTG would call and lose, but the Button showed his cards thinking I was the only one in the hand and he had won. He had K-K. Pandemonium.

The UTG threw his hand away 7-7, and said he would have called the Button's all-in had it not been for the showing of the hand. I busted on the bubble next hand and felt the whole thing was badly handled. What should have happened?

My opinion

I would of went all in sooner. Its not worth milking it for a buck go for the loose aggressive about five percent of time especially when low on chips. Because you haven't played loose aggressive in a while players will fold thinking you have something. A bluff.
