A boy in band that is your boyfriend only during the band trip. He asks you out on the bus there, and breaks up with you on the way back. There are never any hard feelings, because you only said yes because you were desperate.
Annie: "What? Jake broke up with you? But you two made such a cute couple!"
Dana: "Whatever, he was just a band trip boyfriend. It's not that big of a deal."

A band-trip boyfriend is acquired in the following manner: a single band geek sits beside another single band geek on the band bus over the duration of a band trip (especially a long one). Close quarters and raging hormones result in a couple, especially in middle-school scenarios where "having-a-boyfriend" is considered an essential mark of status. Because of sheer desperation on the part of some band geeks, it's nearly inevitable.
Susy sat next to Jake on the band trip to Florida. They're going out now; it's a perfect case of Band-Trip Boyfriend Syndrome
