When someone forgets to tell you "thank you" and sometimes to coax that person to say those 2 words you are a smart ass by saying "your welcome". Well, to eliminate having them to actually say the 2 words, you say this one word and it means everything all put together. Maybe even considered an insult.
You're at a party and you just handed someone a beer, they take it but don't acknowledge you. Say to the person "Thancome" or "Your very Thancome"
