Oh man!!! that's what, Once we went to a cafeteria with my friends, so they ordered this karak, then one of my friend ask me 'joe what u gonna have,shall i order one karak for u' actually it's sounds me like 'katak' with the curious voice, i told him 'no no ,,, i don't want 'katak' gimme one tea with milk' then they all laughed loud, man i was very shy,,, until now i was bit confused about this karak.
