Similar, yet distinctly different from the term “trippin’ balls;” used for the female gender.
Vag refers to vagina, the female reproductive organ.
Trippin’ Vag is the act of a female exhibiting irrational behaviour; due to the overabundance of estrogen.
"That bitch is trippin' vag!"
"Are you on the rag, because you’re trippin' vag?"
"Calm the fuck down girl, you’re trippin' vag."
"Ever since my wife woke up, she’s been trippin' vag non stop"
