Meaning of a sentence please !!

Marina • Happily married. Welcomed our 1st baby girl Angel 5th of December 2018 Second baby girl due July 2020 💕

Hello all

I am French and just received a video from our daycare provider of our toddler girl.

She keeps them at home because of Covid right now.

At the end of the vidéo you can hear her say to another girl “don’t sit there or Coach will bump you” (Coach is her husband)

What does bump mean please I can’t find a clear meaning online.

She repeated that phrase 3 times and it was not “bump into you”
