Are you serious? Let'er rip! I am marketing a special grunt tube if you are worried about it! It's $39.95. NO RETURNS!!! HAHAHAHAH!!!
If you are having a problem try buying some "beano" or get 2 of those cough suppressors, paint one brown so you dont mix them up!!!!!
Why would you not fart? You think a deer can sniff it and think " Oh, that's Bob over there, I know the smell of his fart anywhere".
If a deer is downwind to smell your fart, it smells your actual scent as well already. Don't sweat it.
DUDE... Deer Fart, so I just stand up and fart in their general direction! I thought bodybuilders never farted anyway
