"Mother I'd like to fuck"
A mother, usually in her middle ages - that despite giving birth to your best friend, is still hot. It's quite common for teenage boys to befriend someone only because their mother's a "milf".
"Liek, omigah - Dude, you're mother's a milf!" -fapfapfap-
Another form of the internet term, lol
. It's often used to poke fun at people who lack any proper grammar skills, or are just downright retarded. Can also be used when someone makes a really lame joke.
