A new piece of 1337 derived from the combination of fucking and pwn, thus to 'fwn' is to fucking pwn, or pwn to a very high standard.
I pwn you, n00b.
Yeah? Well I fwn you, har har, I am teh 1337z0rs.
in either internet shorthand or text, fwn can be a shortened version of the word "phone," by taking the "ph" sound of phone and subbing it with a "f," and then taking "own" sound from the term "pwn," and combining it with the "f"
Phone = fone
own = pwn = -wn
f-one + wn = fwn
fwn and phone are pronouced the same way.

Similar to pwn except a substitute when pwn is too commonly used
