Lip pouting and pursing involves ‘puckering’ the lips, similar to giving a kiss.
It is a motor tic with it being movement-based. It may occur as a standalone tic, with other lip-related tics or as part of a wider complex-tic.
Lip-pouting is a simple tic, and fairly common. For some, the only difference between this and a kissing tic is that there is no contact between the lips and someone/something else.
Occasionally this tic may come with an associated vocal tic, such as saying a word or making a lip ‘popping’ sound.
