Ex. 1:
Dude 1: Man, I'm SO gonna get laid hittin' on chicks at work.
Dude 2: Dude! You gotta stop that, you're gonna get fired or kicked in the nuts!
Dude 1: Dude! Don't play the dude card on me! I'm yer bro!
Dude 2: Dude! I'm not yer bro! And if I DON'T play the dude card on you, yer gonna get kicked in the nuts! You OBVIOUSLY have NO CLUE what yer doing!
Ex. 2:
Dude 1: Bro, I got so wasted last night I broke my face on the railing!
Dude 2: Dude! This is NOT something to brag about! Yer face is still bleeding! Go to the hospital before I slip and sue you for fallin' on my ass in your face-blood!
Dude 1: Dude! Do NOT play the dude card on me when my frickin' face is bleedin'! OWWWW! Take me to the hospital!
