Jamal : Oh so we’re having people over tonight? Let’s invite Nate
Phil : Fuck no dog Nate’s a dirty blanket. Every time he pulls up he brings an 8 ball and I end up nose deep in some Columbia Bam Bam and a mentally ill Latina. I love the guy but I got work tomorrow.
Negative:
Don’t invite Jorge to the function, he’s a dirty blanket. He always shows up off the pookie and scares the hoes.

When an uncircumcised penis touches tip-to-tip with a circumcised penis and blankets the head with its foreskin. Similar to a Chinese finger trap!
Chad: Dude, did you hear what Heath and Jake did this weekend?
Noah: No, man what happened?
Chad: Heath was passed out at the party and Jake took off his pants and gave him a turtleneck blanket!
Noah: Radical.
