Rule of 5 

Spread your hand out and point to each finger and say "I . . . don't . . . give . . . a . . . fuck". It means I could care less, whatever you say or do has no effect on me. It is used when it is inappropriate to actually say "I don't give a fuck"

Boss: I'm gonna have to suspend you for 2 days.

Me: Rule of 5.

Ex-girlfriend: If you don't go to the concert with me I'm gonna break up with you.

Me: Rule of 5.
