Get the flake mug.
Irish slang for being too tired to do anything.

Similar to flaking out where the person flaking would bail from a planned event, flaked is if the person never even accepts going in the first place.

Can also be used to describe you being in comfort
"I went to bed flaked, got some decent sleep."
"You coming out man?"
"Nah I'm too fuckin flaked right now, can't be arsed"
