Get the or nah mug.
A fun and popular way to say "or not" usually said by tweens and teens.

It is always found at the end of a question and is usually preceded by a clicky noise made with the tongue.

When said, the facial expression usually contains wide eyes and a mouth open wide vertically instead of horizontally thus making it funny. This is the opposite of how ones face normally would look when asking a regular question. Example: tight lips and partly closed eyelids.
