American Phrase Post
One phrase that Americans often use when

asking for permission in an informal or relaxed situation is the phrase “it is cool if...” For example, instead of saying “can I go do this?” or “may I go do this?”, you could say “is it cool if I go do this?” Who you use this with will depend on your relationship and the setting.
More Examples:
“Is it cool if I leave now?”
“I have to go take a test, is it cool if we do this later?”
“Is it cool if my friend stays the night?”
