Ello guise. Another game blog.
It's basically a person asking the others when the last time they did some specific thing was, and the others replying. It can get pretty funny, and sometimes it's hard to think back. You don't have to give exact dates or anything, but just a small idea of about when it was.
Example:
User 1: When was the last time you brushed your teeth?
User 2: This morning, lol
User 3: ...I rather not answer this question...
Etc.
Why not try it out? :D
