eashaar
Eashaar is the name of a person who lies to your face and then laughs in your face. They are the worst, always thinking they’re better than you, even when they’re clearly not.
You: "I’m gonna beat you in the test." Eashaar: "Sure, whatever." Then they cheat and get an A.
You tell them a secret. They tell the whole school.
You: "I’m gonna beat you in the race." Eashaar: "Sure, whatever." They trip you and win.
