Also referred to as #Rash, an all too common twitter affliction of the over use of hashtags.
A major cause of HashRash is politics, resulting in tweets that say nothing but "#TCOT #TPOT #Porkulus #Stimulus #Congress #Teabagging #Teaparty #Fixednews #NObama #Iran #Pakistan"

A good indicator that can tell you if you are allergic to hashish. Shortly after smoking some, you notice a giant rash on your gooch.
