Word 5:

I get so annoyed when you are walking down the corridor quickly and efficiently and you get stuck behind one of two things: a group of people standing in the middle of the corridor obstructing bipedal traffic; or someone walking about as quickly as a slug on downers. I wish people would perambulate outside, where they are not making commuting through corridors even less systematic than it already is. Okay my small rant-the-size-of-a-novel is over, back to business!

Perambulate - Walk around in a leisurely manner
