swamp dick
the sensation you feel on your penis when:

A) you take a condom off of your dick right after you bang a nice hot and wet vagina.

B) you get hot and sweaty and dont shower for a few days.
A) Will: Dude, I just banged the guts out of this slut in my car, and when I took the condom off, my dick felt all slimey and weird like it was in a sauna for 3 days.
     Me: Sounds like you got a wicked case of swamp dick!

B) Will: Dude, I just got back from a 3-day ass spelunking expedition with my boyfriend, Chris, and it feels like I got a sweaty rodent in my pants.
     Me: Sounds like you got a wicked case of swamp dick!
