When you're motorboating a girl whose breasts are too small and your nose runs aground on her sternum.
Aw man, I was fooling around with Michelle last night, and you know how much I like motorboating, well I was totally beaching with her. That girl is a B cup at best.

Have you seen Carly's breasts? Huge. That girl is unbeachable.
