Let's add to this idea. The 24 year old is a posh girl from a wealthy family and never been in a fight in her life. She gets into a scrap with an 18 year old whose smaller than her but comes from a rough neighbourhood and has been in many fights, so she's mean, cruel and knows every dirty trick there is. The big girl is thrashed! And a friend of the 18 year old is present who films the fight on her phone and puts it online. Even worse for the posh girl is that her dress got pulled down in the tussle, and as she wasn't wearing a bra her tits were exposed. And filmed! Soon she's being taunted in the street by girls who've seen the fight, and jeer her for having lost to a smaller, younger girl, while guys smirk as they make crude comments about her boobs.
How's that for humiliation?
