First post! Take it fwiw totally just a suggestion!
There seems to be a distinction lurking in these posts that I think could clarify things. This is lifted from phish dotnet so not taking credit for it.
When a single member of the band plays another song's melody, it's labelled as a 'tease'. No need for all the others to pick up on it. When everyone hops on and plays the different song it's labelled as a 'quote' and if it continues beyond a few measure a 'jam'.
My thinking is that a ton of teases that are intentional and obvious will be missed if we're only calling it a tease if the whole band plays it.

Midnight Rider has Makisupa tease (by just about everybody) and Hot in Herre vocal tease (I think Brian if I remember right)
