glyphomaniac 

a crazed user of glyphosate (weed killer) in an endless crusade against invasive weeds in the garden.

She's a lazy gardener. She doesn't even try to pull out the weeds. She's just a glyphomaniac.

Gymphomaniac 

Like a nymphomaniac, but walks with a limp; a horny, overly sexual person that also limps.

"Uh-oh, here comes Gimpy Glenn."
"Stay away from him, I hear he's a Gymphomaniac"
