A millie is a Northern Irish FEMALE Chav. The term has been around long before chav existed.
It goes back to the days when the rough and working class fishwives worked in the Linen Mills, hence millie.
The male equivalent is 'spide'. Its roots and origins are unknown, but spides normally hang around corners with massive carryouts and hurl abuse at passersby.
A derivation of 'Pulling a Millberz',a 'Millberz with Pace' is the act of running to catch up of a group of supposed 'mates' who have shunned or ditched you.
To 'pull a Millberz' is the act of standing between two people who are dating, or crucially, potentially dating. The act often involves both arms slung around the lovers necks and saying, "How are you guys then."
The entire concept of the idea is frowned upon by society and has been punished before by severe banter and exclusion resulting in the need for a 'Millberz with pace'.
It is believed the first Millberz was pulled in a remote English city called Worcester. It is alleged that the name comes from the original offender, but has never been confirmed.
