'Earthy' person who takes pride in avoiding showers and has absolutely no problem with hairy armpits and destructive body oder. Often times proud of this offensive condition, an 'earth biscuit' is likely to smoke a lot of pot and probably has a garden with dying vegetables they forget to water. Likely to listen to hours and hours of ridiculous and monotonous bands who also take pride in stinking.
'Hey Jon, that chick Sarah looked kinda' hot at the rave last night, to bad she doesn't shave her legs.'
'Yea, Steve, I bet her pussy reeks like dead fish, to bad she's a fuckin' earth biscuit man, good ass gone to waste'
