When a girl is giving you head and she sticks a finger in your asshole; Aggressively, without warning. Itรขยยs a blow & bust, simultaneously. When you know, you know. Blust.
I was weed whacking in the yard and the the old bowler lady from next store caught me lookin, ass up, she snuck in from behind and before I knew it I had blusted.
