Alex Jones is welsh slang for an angry person who breaks objects belonging to others. Others describe this being as having an unusual or 'funny' looking face. The description is mainly used by welsh people but has also been adapted by a few english communities. It may also describe someone who is a combination of a lot of negative things such as being angry, funny looking and unhumourous.

verb; the act of passing your body through a closing door, as opposed to holding it, leaving another individual with the horrible fate of having to take the effort to open it. As seen in Indiana Jones(except you'll look like a douche if you drop your hat or if you do it when your alone).
