Get the Bummug. A "sleepy bum" is a playful or informal expression that typically refers to someone who is feeling lazy, tired, or sluggish, often because they want to relax or sleep. It’s a lighthearted way of describing someone who’s feeling particularly cozy or inactive. It can also be used humorously to refer to someone who’s not getting up or moving around much, like a person who just wants to keep hitting the snooze button on their alarm clock for hours on end.

Get the Sleepy bummug. Doesn’t have anything good going for themselves, nor do they care to. They’re most likely a deadbeat father/mother, lives with other ppl, have multiple women/men so they can have a place to crash. And they keep up more bs that Wendy Williams.
