When the lads get together to bum it out behind the shed
Me: me and the lads are total bummer boys.
Lyric from Chappell Roan's "Super Graphic Ultra Modern Girl". A man who is mediocre at best and brings you down at worst. Overall ruins your day.
"Girl, my ex is such a hyper mega bummer boy."
"I don't need hyper mega bummer boys in my life. Girls are better anyway!"
