Term created by long suffering girlfriends who have to sit and watch the bfs play COD all the time.

Frag out is to sit down and chill out, do nothing and watch cod being played presumably.
S: "oh man Al is playing cod again, i'm gonna frag out"

B: "yer J too... i'm gonna frag out too, lets text each other about nails and shoes and stuff"

An announcement made after you fart. Used as a warning or to claim the fart. In the military the same announcement is made when you throw a grenade.
Mary: Fart Frag out.
Jane: Eww. Thanks for the warning.
