When you haven't done something in a long time.

A swimmer

ghetto way of saying in a long time

I period of time that is most likely longer then a minute.
Rather it be the past, or future, you can use the term.

what you say when someone tells you to do something but your too lazy to do it.

A phrase used to make people think you are going to do what they say 'in a minute', however the task is almost always never done as the person is too lazy. It is most effective when used to piss someone off. Goes well with whining noises.

Another way of saying farewell (like BYE), especially over the phone.
