Speed boating 

When a penis is inside a vagina or ass and the vagina or ass farts or queef's.

I was motor-boating your mom's tits. Then while fucking her she queefed and was speed boating my dick.

Speed Boat-ing

1. To procrastinate to the point of avoiding the thing completely
2. To do a job so badly nobody wants it, anyway.

Boss: What is this shit?
Employee: I was Speed Boat-ing...
Boss: You're fired!!!
