The phrase comes from Russian internet slang where a mamont, or mammoth, means a naive person who is easy to trick, especially in online scams and fake deals. Zaskamila is the feminine past form of to scam, so the line implies she scammed the mammoths. Clips using the sound spread as a short reaction meme on social video and in chats, where creators label the victim, caption the moment of realisation, and reuse the catchphrase whenever someone is clearly being fooled.
