So folks, mere dost ne aaj mujhe ek random gc mein add krr diya. Pura group so called chigma dank humour anti Indian anti feminist logo se bhara hua tha. Usme ek haryanvi ne ek bike crack krte hue voice note bheja toh saare uska majaak udane lge (vhii purane haryanvi stereotypes) haryanvi jaahil gawar hote h uneducated hote h Orr vhi jaat ko j.aat wala slur use krne lge then uss ladke ne comeback kiya (we are superior from you). Hum zyada sports mein h zyada medals laate h and Hmare pass 'high steepe DNA' hum sbse zyada closed h indo aryan race se. And that f word high steppe dna mene pehli baar suna apni life me.mein bhot curious hua and then mene google search Kiya toh vha pta chla ror and jaat has the high steppe DNA? Toh folks isme kuch reality bhi hai ya totally nonsense h.
