look up any word, like fleek:
 
1.
The point of apex in female orgasm where her legs start to shake uncontrollably.
She had the sexquakes after we got done for an hour.

2.
the act of having sex so intense that the bed shakes so turbulently that it feels like an earthquake
I was fucking this bitch so hard that she thought there was an earthquake happening when in reality it was just our sexquake
