Gass'n 

1. When you freestyling and you just in the zone. Or when you're pulling some baddies.Just gass'n, Whew! Or like when you get away from cops after the pursuit. Gas. You could just be walking down the street nonchalantly and find like ten bucks. Like, Ugh! Just Gass'n!

The Bay Area got hoes. Folks be just gass'n in theseSacramento to San Jose streets, just shedding octane through the Tank.

Nan-Gass 

The fabrication or exaggeration of an anecdote/scenario, or just general bullshitting from an old relative, usually Nan/Grandmother.

Can be rarely used as a derivative of "Gassing" in a general context w/out an OAP involved.

e.g #1
Nan: "Stop leaving that television on standby, you're charging me in excess of £50 a day on electricity bills!"

John: "Oh, behave it's like 14 pence a day. Stop Nan-Gassing."

e.g#2
Granddad: "Have you noticed the evil glare in our neighbour Sally's eyes whenever you make eye contact? She must be a serial killer."

Jason: "No, that's a genuine Nan-Gass, Granddad."
