Usually an old bag or ugly bag you pick up or sit next to on a jet or plane trip.

Refers to the bag you spew in on the plane.
"Hi my name's Tish." "I guess we'll be sitting together for the next 20 hours?"

"Fuck'in great!" "Sitting next to a Jet Bag!"

"Well hello and fuck you to pig!"

"Yeh!" "Yeh!" "I'll fuck you later bitch!" "Just give me a minute."

Get the Jet Bag mug.
when your body clock is confused into thinking it has jet-lag... caused by a weekend of nocturnal partying and chemical abuse.

Causing the inability to sleep on a Sunday night and waking exhausted on a Monday morning.

The shortened from. Simply: Trash-lag
Joey: oh my god, I had NO sleep all weekend, then went to bed early on Sunday night and barely got a wink even though I was exhausted.

Katie: Your such a trash bag. You def got a case of Trash bag jet lag
