A novelty playing card with an erotic picture of a dude on the back, typically spread eagle with well orchestrated junk presentation. Often given as a gag gift to females but more appropriately hidden in bags/clothing/rooms of dudes for later accidental enjoyment.

Verb form: The act of placing a dude card in someone's gym bag or room. To be "dude carded."

Dude Card (n.) - The Dude Card is a metaphorical "card" that signifies all that means being a guy. It is used so that other Dude Card holders can let a fellow dude know when he is not acting like a guy.
