A style of singing in current popular music, specifically R&B, where the singer incorporates a lot of "runs" and extra notes to showcase their vocal abilities, resulting in the singer looking like he/she is trying too hard to sound super-talented. Often accompanied by dramatic hand movements in synch with the notes being sung.
The version of "Lady Marmalade" sung by Christina Aguilera, Pink, Mya, etc. is nothing but a bunch of vocal gymnastics.
