Gargantuar 

An enormous, powerful member of the undead race led by Dr. Zomboss that attacks by smashing any and every form of plant life with the intention of felling this massive zombie in its path. If the Gargantuar reaches a weakened state, it throws its ally, an imp, in hopes of it trying to acquire the brains of the homeowner.

(Suburban almanac, PVZ1)
"When Gargantuar walks, the earth trembles. When he moans, other zombies
fall silent. He is the zombie other zombies dream they could be. But he still can't
find a girlfriend."

Guy 2: Ya, that was Gargantor the Baconator.

Gargantutwat 

A person of large structure that not only participates in twat like behavior but is basically a twat all the time. They tend to have sister wife hair and have shoes a small child could sleep in.

Oh look there's that gargantutwat. I expect she is off to tell someone how to do something she has never done before.
