What is I Can't See How That Happened?
Something to say when you see a particularly unfortunate looking woman with children. It's considered a subtle way of pointing out a troll in the vicinity.
Guy #1: Oh my God, that woman hurts my eyes. How'd she get so many kids?
Guy #2: I can't see how that happened.
Guy #1: Blah blah blah blah blah.
Guy #2: (nods in a direction) I can't see how that happened.
Guy #1: Thanks, I didn't look directly.
