You are a victim of Swamp Dong when a girl that you are fornicating with squirts (female ejaculation) while you are inside her, saturating your balls.
I spent a long time cleaning up after last night when my girl gave me swamp dong several times.

When male genetilia is all hot and sweaty; like swamp ass (swass) or boob sweat (swoob).
It's like 104 degrees outside and these polyester shorts are giving me a bad case of swamp dong.
