I can just see the XKCD for this one. Male programmers are talking in a group. Female programmer walks up; they fall silent. "What were you talking about?", she asks. "Uh..." one says, and falls silent. Awkward moment. She walks away, saying to herself "they don't like me". Back in the group, guy A -- "I wasn't sure if it was a reportable word." Guy B -- "You just gave her the silent treatment because she's a woman."
