Listen up, simplicity is perfect.
This is without a doubt the perfect comeback when challenged, insulted or demeaned whether it be verbally or electronically.
The best way to effectively say this insult / diss is dependent on each individual scenario.
For example: Susan your best friend calls you a bitch out of nowhere for sleeping with her boyfriend, Brad. Your reply is a calm
who u. She will then most likely and stupidly reply "who me" this is where you make that bitch Susan feel like an
absolute moron and you then
finish her off with "YA U".
Another example: In a heated verbal debate via text or in person, insults are being thrown and the only way to successfully achieve a successful and enjoyable victory is through aggressively asserting a "who u" thus ending the argument.
A more joyful example: You are intoxicated in your friends minivan coming back from the bar in downtown
Royal Oak passing through the privileged city of Berkeley and Birmingham. You then see someone minding their own business walking with their dog. Being intoxicated you yell "
WHO U" at the top of your lungs. Not only does this completely confuse the individual for weeks and
startle the individual momentarily, but it also provides you and your friend group with the best laugh of your life. This scenario is highly recommended.
TIP:
Mix and match different voices, pitches, vocal ranges and lung expenditures to find your perfect "who u" for any given scenario.
