But with an STD Grab Bag you can pull out: genital warts, syhpillis, chlamydia, or ghonnorea. Yay!

A fucking splendid hardcore punk band out of the the Chicago suburbs.

Originally called the 'Target Rats', they decided to change their name and asked the crowd at a show for ideas; STD Grab Bag was the one they went with, and have remained since.

ME: Hey Jesus, let's go to the STD Grab Bag show!

JESUS: Fuck yeah!

When you mention to a potential sexual partner that you do not have condoms on you, and they reply 'So?!?' without hesitation.

Man I'm waiting to see what I caught from that std grab bag last night. That girl didn't give a damn that I didn't have condoms on me.
