I never use that word unless I mean it, I have been caught up pretty bad knowing what the respond back when I got the L bomb dropped on me.
However I think it has great addition to your arsenal, if you can deliver that word with not too much seriousness, but with good dose of playfullness it can be a killer. I have a friend who does it all the time, and believe me that shit is crazy even over the phone, he knows his shit.
However this might vary depending on culture and language. Its never the same dropping the L word in english as its in chinese.
