It is an insult but it is kinda strange to call someone a mole.
A mole is a very ugly creature so I expect, in other words, she was calling you ugly
then she is a racist
It is slang or gangsta for kid or buddy.
He likes you more than just a friend sweetheart. Call him boo next time he calls you that and see how he reacts
rather its a joke, or there not dead
she thinks of you as a great friend or a brother.
she is very special friend.
if it is a boy then they are flirting. if it is a friend then it is a nickname
he is being nice Well, my best friend calls me sweetheart and he is gay.
A friend calling you bossy and laughing weird can indicate that they are getting annoyed with you, but this does not mean that they do not like you.
It means that he wants to hang out bro
It means she does not want to have sex with you & she just wants to be your friend.
Almost nothing, especially if he's British.
