1. a girl bummer is a guy who always seems overly friendly and accommodating to women. He gives the impression of being the friendliest guy in the world but actually is trying it on with every girl in sight in the most underhanded of ways. He is usually despised by his peers for this behavior due to the great amount of attention he recieves from girls who just think he's a friendly guy. Under his warm exterior lies the heart of sleaze monster.

2. The other kind of girl bummer or GB really is a nice guy but is so accomodating to every woman that any manhood he had shrivels and dies.
Girl 1:"hey tom's here!!"
The Girls:"HEY TOM!!!"
Tom:"Hello ladies how are you?"
The guys:"Girl bummer!! Your a fucking GB go home!!


GB!! GB!! GB!! GB!! GB!! GB!! GB!!

Hot girl bummer is the definition of finding a girl who is participating in hot girl summer and posting pictures to draw attention and likes using her body or sex appeal. Using hot girl summer as a front for female empowerment and loving their body, but instead just want male attention and boost social media likes using thirst traps.
Damn hot girl summer, nah that’s a hot girl bummer she’s not that committed bro.

The song ‘hot girl bummer’ is an anthem for introverted people who are shy to get out in the world to have fun just like everyone else. Again, this song has nothing to do with Meghan Thee Stallion’s ‘Hot Girl Summer’.
Let's have a hot girl bummer today.

Woman that changes hair daily, sharp with the tongue, plays loud and inappropriate music and doesn’t take crap from no one
Brigette, with her new red highlights, turned on Hot Girl Bummer at 805 am and disturbed everyone and wouldn’t turn it down. She may be the true Hot Girl Bummer.
