Women who seek out comedians to have sex. Comedian groupies who hang in comedy clubs to pick up the guys after their performances. Similar to star fucker but these chicks stalk comedians.
That woman is a chuckle fucker who did the entire cast of SNL.
Someone who stands around at work telling jokes, talking, taking excessive smoke breaks and/or taking part in any other number of lazy ass things to keep from real work so that people who actually work can get pissed at them.
James: I hate Rod, he's a no-good chuckle fucker.
Liz: I know, he's spends about half the day talking to Jake in the back.
James: If I don't get help with the inventory one more time I'll kill him.
