1)Short for 'double post', when someone makes two posts that say
the same thing. Usually, a dp is made because
the person clicked the 'post' button twice, or is just spamming.
2)Short for 'deep pussy', usually a larger woman has one. A pussy
that goes on and on.
3)Short for 'double penetration', or when a woman or girl has a penis in her vagina and in her ass at the same time.
1)A user called whachtameanboy69 always dp's on my BraveNet forum. It's
annoying.
2)I fucked Brent's fat old mom
last night. She had such a dp, I could stick my whole 9.5inch dick in her, and there was still more room!
3)Damn, my new
girlfriend Monica is into dp. She keeps asking me if my buddy Kent can join us when we fuck.
