This happened years ago. I washed my gi with other clothes, grabbed it out of the dryer, and rushed to class. Half way through class, I got up from taking a roll and saw a pair of MY underwear in the middle of the mat!!! It must have been stuck inside of my sleeve and it flew out when I rolled! I snatched it up and hid it in my bag. Luckily, I was partnered up with another woman and we had a good laugh over it. I don't think sensei or any of the other guys saw what happened and we didn't tell them why we were laughing.
I guess you could say you made a bloomer!!!Just as well it wasnt a pair of boxer shorts or worse a gents trendy thong.
I must say I would had I been there I would have creased myself laughing if I noticed the incident.
All jolly fun eh? Cheers, Joe.
