Definition of Foetus: The Foetus is the nickname for a particular sex god by the name of Jonpaul Michael McGrane who lives in Coventry in the West Midlands. The name grew about through some light hearted banter when he was a young lad around 13 or 14 and used to have a skinhead of a haircut. Being a young and hairless lad they decided that his appearance resembled that of a foetus hence the nickname. The nickname grew popular throughout the dol y moch group of 5th - 10th of November and has stuck. His two best buddies are Lee 'I Killed A Seagull Hopkins' and Dave 'Show Them The Whole Thing' Nurse.
