a person who quite simply can be defined as a plagueing cunt! someone who never leaves you alone E.g. facebook messages, spamming your instagram etc. usually an ugly bastard of a yoke who thinks shes unreal!
A standard girl at Bournemouth university who loves her house music and goes by the name of katie.. she will find you on tinder and start the PESTING, the art of Flirting with an obvious attempt to get you into her lair so that she can do unsightly things to you. Normally she will do this for free but sometimes you will end up paying for it with mental and physical scars. Be aware of the PEST beast as this will be heading your way if you LIKE her on tinder, you have been warned.
