cantaloupe weenie
During the engagement of sexual intercourse, one's penis might "slip out" and come into contact with a non-penetrable area, resulting in a "broken penis". After some time the penis in question will become inflamed and swollen imitating a sort of bulge, or cantaloupe shape on the shaft of the penis or weenie.
"Last night i was getting it on when all of a sudden i slipped out and nailed her taint. I think i broke my dick, man I'm going to have a fat cantaloupe weenie."
