victory call
About a month after you have sex with a girl, when she calls you to tell you she got her period. You scream and jump for joy, feeling victorious, hence the "victory call"
-Yo, this girl gave me the victory call today, I swear I never been happier.
-So she not pregnant?
-Naw, dawg, she clean and I'm free!!!
-So she not pregnant?
-Naw, dawg, she clean and I'm free!!!
