look up any word, like bukkake:
 
1.
cumming, orgasming, blowing your load, ejaculating, producing pig sauce

slip a gear
slips a gear
slipped a gear
slipping a gear
I hope I don't slip a gear too quickly with Marcy tonight.

Marcy, "He always slips a gear when we do it doggystyle."

She begged for her partner to keep going and not cum yet, but on his next glorious thrust he slipped a gear and collapsed in exhaustion

Bill (in mid intercourse), "OMG I am slipping a gear!! ohgasgd!!!"

Marcy, "Damnit!!"
