Credit: Associated Press Ryan Bundy is part of a group that has taken over a building at Malheur National Wildlife Refuge in Oregon. Some are calling his self-styled militia "Y'all Qaeda" and "Vanilla ISIS."

The gunmen who have seized a federal building in Oregon claim they're patriots.

But on social media, many are calling the self-styled "militia" terrorists -- and mocking the group that has taken over the Malheur National Wildlife Refuge headquarters with derisive nicknames.

Some are calling them Y'All Qaeda:

Whomever came up with #YallQaeda to describe the Oregon militia, I take my hat off to you. And then put it back on and take it off again. — Colin Miner (@cominer) January 3, 2016

Whoever coined the hashtag #YallQaeda is brilliant. Redneck terrorism has descended on Oregon. — PatOndabak (@PatOndabak) January 3, 2016

Since the gunmen for the most part do not appear to be from the South, others prefer to call them #VanillaISIS:

#YallQaeda makes no sense to me because the militia people are from the West and Upper Midwest, not the South. Have to go with #VanillaISIS. — Brandon Friedman (@BFriedmanDC) January 4, 2016

The emergence of #VanillaISIS in Oregon sparks fears of radicalizing disaffected hipsters in Portland. — Khaled Bey (@KhaledBeydoun) January 4, 2016

#VanillaISIS and #YallQaeda. Oh Twitter, I love you so much. xo — Brew Me (@poguemahonebrew) January 3, 2016

Still others have taken to using terms such as #YokelHaram and #al-Shabubba, and say the group is waging #YeeHawd.

Some are even making fun of the group for its choice of target:

You know you're a badass Tea Party patriot when your militia takes over an unprotected bird sanctuary — Stonekettle (@Stonekettle) January 3, 2016

Every successful revolution starts with takeover of closed visitor center with gift shop. #OregonUnderAttack #YallQaeda — Lars Petticord (@fatdownjacket) January 3, 2016
