Condom. Short for "French Letter," a term used for condoms by soldiers during the two Worlds Wars in Europe, but almost never spoken in full.

FL

a term commonly used to abbreviate the sexual toy, "fleshlight" used as a masturbation aid. Often two people, or a small group, will use the term to make others go crazy trying to find out what FL stands for, but upon researching FL all they find are statistics on the state of Florida.

Ynohtna-"yo tap you got that ""FL""?"
Tap-"uh? ya... ""FL!""."
Group-"What are they talking about?"
