What is demtriv

“Demtriv” doesn’t show up as a standard English word in major dictionaries, so it’s most likely a proper name / username / made-up name rather than a defined term.

From what I can find online, it appears in a few places as a name people use, for example:

• a Facebook page called “Demtriv groceries” (Facebook)
• a Tumblr post where “Demtriv” is the name of a D&D campaign character (“Demtriv the polar Ursine”) (Tumblr)
• a forum story where “Demtriv” is used as a character/person name (NationStates)

One strong possibility: you meant “Dimitri” (very close spelling). “Dimitri” is a given name, and it’s also used as slang for DMT in some contexts. (MedicineNet)

If you tell me where you saw “demtriv” (a text, a game, a class, a meme, etc.), I can pin down which meaning fits.
