A slang term used to refer to the collective Jewish population (or a certain number of Jewish people), almost certainly used in the context of conspiracy theories revolving around such people. It serves to avoid any mentioning of Jews or similar names or terms for a variety of reasons, including but not limited to: evading word recognition that may ban or mute the OP, or fooling those unaware of the term into thinking nothing of their post(s).
Usually, "long nose tribe" is used within a larger metaphor involving cavemen, sticks, stones, etc. that is supposed to draw parallels to modern, Jewish conspiracy theories.
"Long nose" refers to the common stereotype that Jewish people possess long noses.

"Grug no like long nose tribe. Long nose tribe take pointy stick away from Grug; deemed too dangerous."

"Grug no think holobunga happen. Six million tribesmen no die in 5 years, but long nose tribe say it is worst tragedy"

"Grug see long nose tribe put weird food in river. Now boys in tribe wear skins for women; want forage with women, no hunt like men. Grug confused."
