When you're watching TV and you get a snack (chips, pretzels, a sandwich, etc.) during a commercial break, only to finish said snack before the commercials end.
TV: We'll be back after these messages!
Boris: Shit man, this show kicks ass, but it would kick even more ass with some Fritos.
*Boris gets a bag of Fritos*
Boris: Ahh those were good Fritos. Holy shit the show hasn't even started!!
TV: We're back! (Scrubs resumes)
Boris: Ahhh fuck, damn commercial snacks.
