To 'pat' someone is to throw one's excrement, especially faeces, at them.
Ladies may also choose to throw used menstrual regalia instead of faecal matter.
One may commit the ultimate pat by furnishing one's bowel with the necessary materials before positioning oneself directly above the head of a friend, relative or perhaps passing person, thence one proceeds to pat them right on the head.
Alex had been a dick to Katy so she pat him. She pat him good.
Katy's menses had stained Alex's favourite shirt after the pat attack, therefore he fucking killed her dead. Bitch.
a) Pats tend to wear Sketchers (or Crocs), cheap wristwatches, and unisex slacks
b) Pats are normally overweight. In this sense, you cannot tell if 'it' has man-boobs or actual breasts.
c) Pats often adorn shirts with horses, wolves, or Disney characters on them. Tourist shits in general are also the preferred clothing of the Pat
d) Pats sport androgynous haircuts- short, sometimes spiky.
It's a Pat.
