Term used to describe someone who is legendary but they’re so legendary they probably don’t have time for you to say the four syllable word so instead the one syllable word; “ledge” was invented.
Ledge, a noun, short for legend, refers to someone who's just done something so astonishing that they'll be remembered as "that cool dude/dudette/duderino that did X." I.e., an absolute madlad.
A legend in the making.
An individual who is on the verge of a legendary status.
Showing appreciation to someone due to a favour.
Note: The word 'Legend' is often over used for individuals who are truly not worthy of the title. Using the word 'Ledge' can be a more meaningfull fit, without taking anything away from the person.
Billy: Tom really helped me with my assignment man, he is a Ledge!
Sam: 'Joe can you cover my shift on saturday? I really need it off.'
Joe: 'ummm... OK'
Sam: 'Aw cheers mate, your a Ledge!'
