Seeding 

When one dude cums inside another dude who is really horny and he wants to own him with his cum so he pushes it all inside him and makes him take every last drop of it with no condom holding it back

"Brady Quinn fucked me good last night, so fucking good, was an awesome seeding, he owns me"

Polly Seeds 

Sunflower Seeds

I love polly seeds. What are polly seeds? Sunflower seeds are polly seeds! How did they get that name? Parrots say, "Polly want a cracker" and parrots eat sunflower seeds.... so they are called polly seeds!

Seeding 

The act of enabling files for redistribution for Torrents and other file sharing systems.

Seeding at least what you take is important, that is why it is called "file sharing."

Seedy

Run down and shady.

The old casino had ripped vinyl seats and only 3 slot machines. It was a really seedy place.

Seedplanter 

A slut, who most likely has a boyfriend, who goes around strategically flirting with guys on the down low, thus planting seeds in the case that shit goes bad in the current relationship. They may occasionally have a random hookup which always ends with blue balls. Girls who take part are usually a 7+ out of 10. Traits: deceptive, misleading, lots of excuses, generally loose.

"Man, I was proper blue balled last night, turns out she was just a seedplanter."
