Sidewalk Boogie

The little dance you do when trying to avoid someone walking towards you, and you both end up side stepping about three times into each others way before laughing awkwardly and you or your dance-off opponent lets you pass.

I was walking through town today and did the sidewalk boogie with about five people.

Wristslapper

Someone who either acts or is genuinely so stupid that they incite rage in everyone that interacts with them.

Can also apply to the kind of people who think that 'your mum' is a valid point to make when losing an argument.

A: "I was speaking to him the other day. I say 'speaking'... I had to walk away in despair after about two minutes."
B: "Yeah, he is a bit of a wristslapper."

A "I'm not insulting you. I'm simply saying that your opinion is based on something that isn't true."
B: "Your Mum."
