Suh Dude is a viral catchphrase born from a series of Vine videos featuring comedian Nick Colletti and electronic music producer Getter. The phrase is a slurred contraction of 'What's up, dude?', delivered with a specific squinty-eyed facial expression and a signature hand gesture. First gaining traction in late 2015, the meme became a cultural phenomenon for its simplistic, stoner-esque humor and surreal repetition. It is typically used in internet culture to represent a nonchalant, laid-back, or slightly confused greeting, often paired with deep-fried filters or blurry screenshots from the original videos to emphasize the chaotic energy of the duo.
