Dollar bills are cool because you can pass them out to strippers and not feel like a cheap ass because that's pretty much all they get unless you're just dumb as fuck and slip them bigger bills. You can also do tons of things with dollar bills check this shit out.
The cool thing is that my name is Erica. Get some.
Girls can't get boners (thank god) but I'm sure they're no joke especially when you're carelessly putting them in strippers panties.
