Where does suh come from?

Second Life Marketplace

Saying suh dude as a slurred, stoner way of saying “What’s up, dude?” appears to originate with Vine comedian Nick Colletti and his friend Tanner “Getter” Petulla (also a DJ). On March 23, 2015, Colletti uploaded a Vine video featuring Petulla saying (a) suh dude for What’s up, dude?  (often shortened to sup).

Later instances of Colletti and Petulla saying suh dude went viral on Vine, YouTube, and Reddit. This is due in no small part to their own self promotion; in December 2015, they began selling merchandise with suh dude on it. The videos sparked spinoff suh dude memes, often featuring people holding up lazy peace signs or with their eyes half-closed in the same high-seeming way that Petula’s eyes are.


Suh first appeared in print as a variant spelling of sir by at least the 19th century. It’s a reflection of a British English pronunciation of sir. It’s also used to represent sir in Southern and Black English.

Finally, the Korean surname Suh is a transliteration of the Hangul 서, sometimes written Seo or Su.
