Clingy; blows up your cellphone, hijacks every facebook/myspace/twitter posting, coffee break, lunch hour, down time, and instant messaging moment of opportunity to the point of suffication, and sucking every miniscule amount of time and breathe you own thus inducing the need for separtation, and official string cutting ceremony.
ie: "I can't believe that he/she thinks I need to spend every dang second of the day with him/her! A deserted island right now would be like winning the mega million powerball prize!! *gasps for air* HELP I CANT BREATHE, MAKE THAT BUGABOO GO AWAY!!!"
A bugaboo is a whiny, needy, pest of a person that complains about everything and constantly wants something. They will find a reason to be in your face if for none other than to bug the hell out of you. Also, people who beg and bum constantly. People who work in retail, hotel and the service industry are very familiar with bugaboos.
One guy has a clock-radio and a microwave in his room, (both of which have clocks) but he's called front desk 8 times now to ask what time it is-- it's time for him to buy a damn watch. Another guy sits in a diner sucking down free coffee refills and pestering the waitresses, hours after the other customers have gone home. A woman has asked 6 different employees at the store about a brand of shampoo they've already told her they're out of at the moment-- she's threatening to call corporate office now because no one has "helped" her. That chick you gave one cigarette to, now she follows you around constantly wanting a smoke. All 4 of these are examples of bugaboos.
