Here's a few things you might say................
"Yeah, that's a manly smell alright....like a man who has worked all day in a sewer."
"Ya' know you could sell that scum in your pits to Ely Lilly to make penecillin."
"It really ain't the smell, it's the fuckin' burning in my eyes."
"I think your dog took a shit in your soapdish."
"Geeziz man, you could knock a buzzard off a shitwagon."
