This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
捸 is a rare character. It combines 扌 (hand) with 隶, but the exact historical development and original meaning are uncertain.
The hand radical 扌 beside 隶 suggests an action, but the meaning is unclear. Imagine a hand performing an obscure, smooth motion.
For トツ, imagine a hand making a sudden, sharp 'tots' sound as it moves smoothly: tots -> トツ.
