UBH - 'Ugly Back Home'. You know those fat/old/gross/socially inept white guys who miraculously parade around Japan/China/Thailand/Korea (basically all of Asia except Nth Korea) with a pretty local girl on their arm?
They are UBHs.
"At home they are zeros - here they are heroes."
And now that they have found their (only) niche, they're not going ANYWHERE.
Guy: "Ergh. I just saw the worst thing. A fat sweaty white guy in jogging shorts and a WANG t-shirt talking loudly and condescendingly to this hot little Japanese girl, who was nodding and hanging off his every stupid, spittle-soaked word. Dude, WTF? I just wanted to rescue her. And also maybe have sex with her."
Other guy: "Bro, you need to calm down. You're in Tokyo now, bitch. You're going to see a lot of that - you've just witnessed a UBH in action."
When a male participates in sexual activities, including foreplay, sex, or oral sex, with 4 or more females which are below his standards. This usually occurs when one is desperate for any sort of action due to one being extremely horny and is followed by depression brought on by being made fun of for your actions.
Sometimes pronounced with an urban street accent: flippin' da channels.
"I was just flippin' the channels at the hotel after prom with Carole, Ashley, Ana, and Megan."
"Ugh, Sunny you sick fuck where have your standards gone!? All of those girls are uglier than your mom"
