your not to good

Sometimes just to piss people off,but it means that your dumb.Mostly said to be funny.

When someone's cooking is so excellent and superb that you can only describe it as good.

This phrase is not a way of indicating that the listener has the wrong currency for use in payment. It can be used in at least two ways. First, with a negative intent, as a way of refusing service, preemptively, to a person who wishes to buy something. This usage is intended to get rid of or threaten the listener. Conversely, the second usage is a bit of Mafia bravado as a way of paying the bill at a restaurant, or some other establishment as a way of impressing the listener or putting the listener in the speaker's debt. In this case, the exchange is stereotypically gendered where the speaker is male and the listener is female.

It is a slang term for sucking dick

when somebody tells you "give your meat a good ol' rub" it means that person is telling you to go jerk off.

hehe boi

Thing mostly said by an adult/parent

To justify controlling something that you percieve as wrong in your life because they want it that way.
Usually it is NOT for your own good, but just because they must force their will upon you.
