Rizz is internet slang for charm and flirting skill, and it became a staple of short-form video humor as creators turned confident pickup moments into quick reaction sounds. This particular clip is credited to Big Isa and circulates as a tiny, two-second voice snippet rather than part of a song or show, which makes it easy to drop into edits, memes and replies. Its staying power comes from that brevity and attitude: it instantly signals smooth confidence without needing context, so it keeps working across new trends, characters and crush jokes.
