Slobby Blobby
Someone who is not only a slob (a person who is lazy and has low standards of cleanliness) but also is on the chubbier side, considering themselves a "blob"; someone who always looks like shit, like they don't care; next level of a hot mess.
"I don't want to be looked at like a slob, which goes back to wanting to lose weight so I don't look like a slobby blobby."
