Definition

A classic '90s Wayne's World-era expression of excitement or attraction, usually accompanied by an imaginary guitar riff. Essentially the verbal equivalent of cartoon eyes popping out of your head when you see someone attractive. Still deployed ironically by millennials trying to relive their glory days.

Example Usage

When she walked in wearing that vintage leather jacket, all I could think was 'Shwing!'
