Which one of the following phrases can be used in the context below in natural English:
- A) Let me go! I won't come along with you. I don't like the company of such people.
B) But believe me; they love you; I don't know why you're spiting me, but I'm sure you'll enjoy it. You just try once.
A) I won't come. I'll stay right here!
B) Ok; suit yourself! ........................... (said sarcastically)
1) Stay / wait there untill grass grow under your feet.
2) Stay / wait there untill cows come home.
I need to indicate: "stay / wait there for a long time (figuratively forever)"
Unfortunately, dictionary definitions couldn't help me to distinguish these two similar phrases and also they do not show me whether these are archaic or not!
