Hello Mato!
Hmm, "Gwee'd" you say? I'm not exactly sure how to put it exactly, but I remember him coming up with the term when we play the forum games such as 'Count to a million' or 'Pass the bomb! xD' And it's basically me just posting ahead before they get to post. For example in 'Count to a million' thread where you post one number and the next number in line is 12345, and we both happen to post at the same time, when my post appears before his one does, he called it being "Gwee'd" at the time.
So yeah, that pretty much sums it up. Hope this helps~
