Another wonderful addition to modern language, from Roger Melly's Profanisaurus

A subset of emoticons, arsecons are used in email communication to describe the condition of an arse:

        Normal Arse =     (_!_)

        Lard Arse   =    (__!__)

        Tight Arse  =      (!)

        Sore Arse   =     (_*_)

        Slack Arse  =     (_o_)
