i used to go to a gym where this one dude would train n get all sweaty on the cardio equip,then when he was done he hide the shirt in locker room n then put it back on the next day,to make it worse he didnt even let the shirt breath or put it on hanger,he bunched it up all sweaty n hid it ???this crap when on everyday till one day the owner threw him out,he did give him choice n said he had to keep his hygeine in check n if hes gonna wear the same shirt bring it home n wash it n everythings cool. when that dude walked by u it was brutal,im talking nasty ass dirty pussy with old rotten sardines nasty smell
