This joke would be fine if you and the person were close friends, as close friends tend to tease each other like this. However, if you are a casual friend or an acquaintance, this is definitely inappropriate as it 1) looks like you were trying too hard to be funny 2) it was crude in nature, usually when two people don't know each other well, they don't cross this boundary and 3) you don't know if the person likes you enough to accept the teasing, which again, is only done between good friends.
A good rule of thumb is to stick with neutral (i.e. not crass or rude) jokes unless you know the person well AND you are completely sure that they respond well to this type of humor.
Bingo. If a close friend of mine made that kind of comment, I'd probably just laugh it off. If it wasn't, it would be a lot more situational. Also, tone, etc. is even harder to determine over fb, and he might have mis-interpreted it as hostile. Its probably best to apologize, say you were just joking and didn't mean it like that, and not do it again.
