When a girl is riding a guy cowgirl style. She begins to countdown from 10, and upon reaching 1 she "blasts off", by queefing on his dick as she jumps up into the air.
Jim: So how was your date last night?
Tom: Great, until the end. Took her back to my place, and she decided to blast off. Picture a leaf blower on your nuts.
Jim: WOOOO BOYYYYY
