— Should we stay at home or go out?
— I'm easy.
When do we use this expression? It is used as a way of saying that one is not hard to please and will accept what someone else decides.
Definition: I'm OK with whatever choice you have made; I'm not fussy and/or I have no preference.
You can use it instead of "I don't care" or "It doesn't matter"
E.g. A: Hey, man! Do you care if we get a sausage pizza rather than mushroom?
B: Fine with me. I'm easy.
