A McLegend isn't like a normal legend. They are the true 'legends'. The kind of person who follows the crowd and calls his 'friend' a legend for shanking up an old nan. We can agree that the technical term 'McLegend' is more of a sarcastic term.
Examples of McLegends:
Scooter kids,
players
people with 'baller' in their
instagram bio,
people with 'single ;)' in their
instagram bio,
people who say; 'You wan sum?', 'Legitimate', 'You wanna fight?' and of course, 'You bladdy legend...'
