Lint Whore

1. Someone who performs sexual favors for whatever you are able to pay, i.e., the lint in your pocket.
2. Someone who will perform a dare for the attention, masking it by demanding something in return, even if it's almost nothing.

"She offered me a blowjob for $3.50 because it was all I had. What a lint whore."
"Bob took the <insert latest social media challenge> because I gave him a dollar to do it."
