Geeks/nerds and some other people on the internet like to add -ey to the end of a word to signify that the subject bears resemblance or is somehow simmillar to that word. Only used where -ey is not a propper suffix to the word, or as a double. Also used by retards who don't realize that they are using slang. (They think that the -ey is supposed to be there)

The window to the skull.

A phrase used by American Indians as 1) A sound noting a joke or 2) A noise stretched out for no reason. (Said just like the Canadian "ey.")

Ey basically means calm down or when someone gets 'hyped' or if one of your friends is talking to a person they like and you say ey to let them know you see what they're doing.

people who smoke too much marijuana get paranoid. they start to worry about being 'in the eyes'.

When your to lazy to say hey on AIM and sound like a prick, you say ,"ey".

Being obsessed with someone to the point of ringing them up every day, texting if not on the phone to them, sellout out mates for them, and having an arm around them at all possible times.

Doing it in a high pitched or aggressive manor to indicate the level of togetherness of the relationship is optional.
