Someone who is a combination of chubby and fat; quite a large body, and an obnoxiously chubby face; will almost always have a poor attitude and grating laugh, which will set the undoubtedly multiple chins into motion
"WTF, who took a dump all over my bed?"
"Ah, your flubby roommate."
The flubbies came to visit last week, and ate all my food.
Dude, stop eating that. You're being totally flubular.
(noun)
Oxymoronic portmanteau word for a half-erect penis ("flaccidchubby"). Often occurs during periods of sexual arousal following excessive alcohol consumption.
When you get a blowjob that takes you to the brink of getting a chubby, but she stops and waits for you to get flacid before she starts sucking your cock all over again. The ultimate blowjob tease.
