An orgasm experienced by a female while cycling or ‘spinning’. The pressure of the saddle on the vulval region, combined with friction between the front of the saddle and the clitoris, can precipitate an orgasm, known to female sporting and recreational cyclists as a ‘cyclasm’.
“Are you OK Donna, you looked in agony when you were going past the 9 mile marker?”

“Oh Tim, that’s really embarrassing - I hoped it wouldn’t be noticed. I was having a cyclasm.”

“Lucky you - with my anatomy all I get is ball-ache!”
