jollymander 

A misheard word, which the person who mishears it, continues to mishear it, in exactly the same way, no matter how many times they ask for the word to be repeated.

K: Hi, my name's Kumail.
J: Camel?
K: Kumail
J: Sorry, can you say that again?
K: Kum-ay-il
J: Camel?
K: KUMAIL!
J: Hi Camel.

K: My name's not a jollymander; fix your fucking ears!

A Confidence trick - To do something easy to get your confidence up before you face the real hurdle.

Pool - If there's a ball by the pocket, and a harder shot - don't necessarily go for the harder shot in case the other balls is accidentally pocketed by the other player. Sometimes it helps to pot these, then go for the others, feeling a little more confident. This is a Jollywanger.
