The most obnoxious, self centered bitch anyone will ever encounter. Irlaines are gold-diggers and use others for their own benefit. They feel as if they can do whatever they want but others can't. Sleazy, whore-bag, but at times can be dependable. When you're down she will be there for you but only until she gets bored and asks for attention. If you meet an Irlaine run, run, run away as fast as you can!

The horrible moment when you realise that you have accidentally done something very slightly wrong which has very bad (usually embarassing) implications for you. This is typically the moment of realisation that you just sent a dirty text message to a close member of family, typically your mother, rather than the intended recipient.
