Stanky Britches 

Underwear that has been filled to the brim with vile human excretion such as anal gravy, sweat, pussy juice, ass juice, butt nuggets, anal hot chocolate, and piss.

"Dude I fingered Tiesha last night, and then I smelled my hand and it reeked of stanky britches."

"I can smell yo britches and they're stanky."

"Hey I gotta change my under wear I have stanky britches."

Stinky Britches 

When a girl has not shampooed her cooter for quite some time and wears the same panties for weeks on end, she develops Stinky Britches. Much like old tuna salad left on the engine block of a cutlas supreme.

Your mom was so slammin until I noticed her Stinky Britches.

Stinky Shit Britches 

A person who reeks of shit because they either have neglected to properly wipe their asshole or they haven't bathed in several days.

Guy 1: "Eww what's that smell?"

Guy 2: "Probably stinky shit britches over there."
