This one time I had a huge zit on my buttcheek and when I popped it the puss soaked through my flannel boxers. I had to throw them away.
There was so much puss that I didn't get it all out on the first go and it got infected.
I ended up having to drain it and bandage it up for 4 or 5 days.
For the next week whenever someone asked why I was walking funny I told them I was butt-hurt.
