Karatastic 

To be the coolest and sweetest person ever. To be extremely funny, except when you're not, but it's always endearing nonetheless. However being karatastic gives you the compulsion to spend a lot of time in Starbucks; but its all worth it once the barista remembers your name and puts a smiley on your cup. Being karatastic also comes with the benefit of being an absolute grinder, meaning you can rack up those 7s in your back pocket. Overall if a karatastic person was on IMDB (for whatever reason) they would get an 11/10 (9.9/10 if we're being humble).

Kara Ly is so karatastic
