Those boys that wear Nike socks just above the ankle, and try way too hard to pull a chick. (Usually by offering to take them to Starbucks to buy them a Pumpkin Spice Latte.)
Girl #1: "Ugh, Jessica, Ben texted me todaaay.."

Girl #2: "Omg Nikki, why do you seem sad? HE'S HOT!!!"
Girl #1: "What the actual frick, Jess.. Haven't you noticed? BEN IS A FUKBOI."

*the second girls phone buzzes and she picks it up*
Girl #2: "W-What the fuck, Ben just texted me too.. Asking me to meet him at Starbucks tonight so he can buy me a PSL.."
Girl #1:"He said that to me too, just ignore him. Fucking fukbois *rolls eyes*"
Girl #2: "Yeah heheh.. Fukbois.."

LATER, Girl#2 decides to meet with fukboi Ben, and notices that she came an hour early, but Ben was already there.

Girl #2: "Hey Beeeen.. (;"
Ben: *stutters but tries to seem cool* u-uhh.. Hey .. Courtney.. ?"
Girl#2: " It's Jessica. *eye roll and smile*
Ben: *still stuttering* oh yeah. Uhm, yo-youre early? Heheh.. *gulp*
Girl #2: "yeah, sorry about the mix up, I-"

GIRL NUMBER ONE WALKS OUT FROM THE STARBUCKS BATHROOM TO GO BACK TO BEN. BUT THEN SHE SEES GIRL #2?!?!? SHE CAME?!?!! THEY FIGHT ABOUT TELLING EACHOTHER NOT TO COME, AND THEY BOTH DEFEND THEMSELVES BY SAYING THEY BOTH JUST WANTED A FREE PUMPKIN SPICE LATTE. THEY NOW HATE EACHOTHER, AND BEN IS STILL A FUKBOI TRYING TO PULL GIRLS WITH PSL'S. THE END.
