I'm very quiet in real-life, but online where I'm more talkative when I'm playing video games with others I've heard this once or twice.
I like to joke around and I can be very direct with what I say. This might come across like I'm trying to tell others what to do or think that my opinion is more important, but that's not true. I know I can't expect this from others, but I always hope that people will just speak up if they have something to add.
