Spaceman
After having sex with a woman (or man), in a bed, the penetrater stands up on the bed prior to climaxing and blows his load in the air (via bouncing), thereby producing a flying semen (spacemen).
Example:
Joey:"Yo Johnny, never guess what I did last night."
Bill:"My names Bill.."
Joey:"I did a spaceman to your mother."
Bill:"I don't even know what that is.."
Joey:"It's like when yo.."
Bill:"You're a tool. Shut up faggot."
Joey:"SAD FACE):"
