mwahaha

A common supplement to a comment in internet discussion,used almost exclusively by relatively innocent females; it generally follows a particularly naughty, empowering, or triumphant moment for them in a discussion. Outside of direct discussion (i.e; in a profile, email, etc.), it often follows something entirely random that they said in what they somehow deem to be a very naughty and rebellious overhaul of common sense.
Generally, if you are a male, any use of this directed at you is a good sign; its a flirty, suggestive word choice (similar to the sound of a kiss), and when used with males it almost implies a sort of lustful blushing. It suggests that said female finds you fun, and is comfortable being playful with you.
