In response to theivam's thread How many ways are there to respond to the question how are you? I'll start.... ****-a-hoop adjective extremely pleased. — ORIGIN from the phrase set **** a hoop, apparently denoting the action of turning on a tap and allowing liquor to flow.
If it is one of those uni aquaintances that you really don't like but keep bumping into I always respond by twitching a couple of times and then saying "The doctor told me I was alright". It always kills the conversation and allows me to get on with my day.
