A bothersome person, someone who's always stressin' over dumb shit or constantly in your face wanting something. Needy, pesty, always bitchin' bout something. People who work in hotels, restaurants or any other customer service jobs are very familiar with these kinds of people. There's a big difference between someone that has a legitimate need and a bugaboo; a person with a legitimate need will get what they need and go away. A bugaboo will keep coming back for no apparent reason other than to bug the hell out of the person/people filling their needs. also: someone that's constantly begging, bumming, gimmegimmegimme. Also; bugabooin', the verb tense of this word
You have a clock radio and a microwave in your room, both which have clocks on them, but you've called front desk 6 times now to ask what time it is. It's time for you to buy a damn watch, that's what time it is, ya bugaboo.

All the other customers left the diner hours ago, but this bugaboo is still sitting in this booth suckin' down free coffee and ordering the waitresses around like he owns the place.

I already told this stupid woman we're out of that brand of shampoo, but she's totally bugabooin' over it. She's threatened to call corporate office about it.

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.
