Similar to bukkake, except the group of men jack off into a bowl of water. The last person to cum then takes a straw and skims the surface of the water in the bowl, swallowing any blobs of cum that float near the surface.
Are you okay? You look sick.
I was a seed skimmer last night.
Hey, invite your friend over who has erectile disfunction to the seed skimming party tonight.
That's just mean.
Yeah but at least I know I won't be a seed skimmer!
