2.
A very hefty fat pussy cat. Usually has no neck, thunderthighs and a big belly that drags on the ground.
That cat of yours is too heavy to take on the plane. He's a Tubcat.

1.
A large Cat, not in stature but in girth. Generally found in the homes of elderly women but occasionally seen held by small children (who are often a similar size to the afore mentioned cat)
Coming from the two english words Tub and Cat, both nouns, Tub either taken from `tub` as in bath tub, or `tubby` as in a cute way to say the latin phrase lardikus assimux, or buttux grandose.
Cat, being the common form of feline.
`My word, Janet, your fat pussy is one hell of a Tubcat!`

Without a doubt, this is one of the worst website ever made. Features a horrible design, poor spelling/grammar, painfully bad use of color, and very FAT cats.
If you don't believe me, just type www.tubcat.com and see for yourself.
The owners of the cats shown on the Tubcat site should be jailed for animal cruelty. Nuff said.
