A hot HOTT HOTTIE is a guy (or I guess it can be a girl) who you think is extraordinarily attractive. The level of attractiveness leads you to want to jump his (or her) bones!
“Hot Wing Hotties”, or “The Hotties” is the trio of BadBoyHalo, Skeppy, and CaptainPuffy. Sometimes Quackity as well. You could also think of The Hotties as CaptainPuffy third-wheeling Skeppy and BadBoyHalo/Happyduo.
