Australians are most likely to use MMFU to mean "my mate fancies you." In this phrase, "mate" means "friend" and "fancies" means "likes." So, in American English, MMFU translates to "my friend likes you."
You might receive MMFU in chat or text messages, from someone whose friend is interested in dating you but is too shy to ask you out themself. YMMV on whether you find that sort of shyness endearing, and how you want to respond to MMFU.
