In office parlance, to "ping" means to e-mail, text or otherwise get in touch with someone. According to Jeff Logan, director of marketing at Dexas International in Coppell, Texas, an offer to "ping you back" is actually a passive-aggressive way to get rid of you.
"I'm pretty certain if someone offers to ping you back, they are not looking for a voice-to-voice conversation, but a text or an e-mail that is more easily avoidable," he said.
Other unpopular terms for "contact" include "reaching out" and "putting out feelers." The latter means "to gauge interest," but Polly Blitzer, founder of Beauty Blitz Media in New York City, said that it "sounds like a creepy pedophile."
