look up any word, like pussy:
 
1.
A male age 19-25 (anything older is defined as "pathetic") who lives in their parents basement. They could be unemployed or a pot head or both. They like to listen to mac miller and think they are dope but clearly they aren't.
Example 1:

John: Dude Sam is so cool, I wish I was him...

Chris: Are you serious? He is a basement booper

John: Ya you right...

Example 2:

Dan: How does Mark have that sick K20 hatch? He works at McDonalds...

Ben: Dude he is a Basement Booper, every paycheck goes into that car

Mark: *hits VTEC down the road*

Dan: fuck that.
