for a song

for a good time call 

Precedes a phone-sex number, typically in a public restroom. Losers on the toilet pay to hear dumb women talk about sex, which spares us the pain of hearing them talk about anything else. It's a tag-line for, well, a tag-line.

For a real one 

For a real one means like you’re giving it your all. You’re about to do something and you’re gonna do it good; you’re doing it for your grandma, mama, brother, best friend, your dog. You’re leaving people sister shook. James Charles likes to use this term a lot.

Him: Are you sure you want to do this?

James: Oh yes sweetie we’re gonna do it for a real one

for a nickel i will

the punchline to a joke i knew as a kid,

i have long since forgotten the joke, but i have always remembered the punchline.

so, if someone asks you to do something for them,
just reply with a southern accent (cause it sounds better):
"for a nickel i will"

friend 1: " blow me"
friend 2: " for a nickel i will"
