Pulling a moaty means: Raul Moat, a paranoid psychopath who killed every person he met because his girlfriend had gotten away with another man, is the source of this phrase. This phrase is for when a Man goes out on a night and makes advances to women but is repeatedly rejected. The individual would become paranoid, uncontrollable, and start marching around in an angry state. Sometimes, the person in distress would leave voicemails to women’s phones and record voice messages. These factors bear a striking resemblance to Raul Moat, thus the Moaty is pulled a Moaty.
