Recently, someone from a UK firm putting together a glossary of social media jargon asked me to contribute. The world of social media jargon is immense, but I realized I've been hearing the word "ping" in a sense that didn't really make sense to me. Ping, v. This is something you send to a computer for an automated response. I've heard it (erroneously) as a synonym for "e-mail" or "instant message." You can look at more social media jargon from their glossary.
