In slang, "yelp" is a verb that stands for writing a review at yelp.com, based on individual experiences about restaurants, nightlife, local businesses, etc. Oh, my God! It was the best waffle I have ever had, I am gonna yelp this.
"Yelp" can also mean complaining or whimpering about something.Are you going to keep yelping about how everyone is selfish?Democrats keep yelping about it to cover for using the government for their own political gain. --The Daily Caller
