'As snug as a bug in a rug' has slowly been overtaken in popularity by the non-elitist phrase for the people: 'as Comfy as G'. Although it is known that it originates on the backstreets of Aberdeen and has slowly spread into England, no one is quite sure who G is and why he/she/it was so damn comfy.
Person 1: mmmmmmm, my new snuggie is as Comfy as G!
Person 2: Dude. You're27.
This describes people who have a comfortable, privileged existence and go online to denounce cops and troops over not shooting someone in the leg who is trying to kill them!
Yes, that cop should have used pepper spray and called the comfy chair committee.
