0 short for collaboration : a situation in which two or more people work together to create, achieve, or promote (= encourage people to buy or use) something:
There are rumored upcoming collabs with Elton John and Mariah Carey.

By doing a YouTube collab, two relatively isolated audiences are introduced to the other’s content.
