This is something you say as you're helping someone over a fence, for example, as a cute sendoff.

What's "sendoff"?
"saying goodbye to someone who is leaving" doesn't sound like 'helping'

Подбадривать, помогая перелезть через забор. Давай, перелазь!

Давай, пошёл!

A sendoff is anything you say to someone to see them off: When you’re kids are leaving for school, you give them their lunch, give them a little smack on the butt and say “Off you go!”

понял, спасибо

a little smack on the butt and say “Off you go!”

“Off you go!” = over you go?

If they’re going over something, you say “Over you go!” If they’re going into something, you say “In you go!” If they’re just leaving, you say “Off you go!”

А по- русски просто «Пошёл!» — хоть через что-то, хоть во что-то, хоть...подальше.)))
