look up any word, like bukkake:
 
1.
1. When a sexy female with generally large breasts give a male with a generally large penis. The female gives the male fast and rough head/handjob.
2. When a male with a large penis shoots out enough cum to fill a glass.
"Dude holy shit she would be a good cum harvest"
"Yeah man check that rack out!"
