"Techniques," as used by prank channel CringeCamTV, is an undefined term meant to confuse whoever he's pranking. Typically, CringeCamTV will walk up to a store employee, show them printed photos of guys giving a light skin stare (his "documents"), and will ask if the store carries techniques, technology, horse shoes, stallion cream, latino oil, lube, or other odd items that he doesn't elaborate on. Again, "techniques" in this context doesn't have a proper definition, but CringeCamTV talks about it like it's common knowledge, adding to the mystery and confusion. Given the suggestive or freaky nature of some of the images he shows, it can be assumed that "techniques" refers to something sexual, but no one can say for sure.
CringeCamTV: "You guys got techniques?"
Store Employee: "Sorry?"
CringeCamTV: Shows light skin stare picture "Techniques. Like, technology type crap. Modified techniques."
Store Employee: "Um... I have no idea what you're talking about."
CringeCamTV: Points to light skin stare picture "So no, like, stallion cream, technology work shoes? None of that?"
Store Employee: Speechless, dumbfounded
CringeCamTV: "Shit, I think I'm gonna have to go to another location."
