Well regarded 

Very retarded. A phrase to be used when the r word would not be acceptable. Prime for work environments or sensitive friend groups.

Guy 1: “Ryan just fucked up another one of my projects. What’s wrong with that guy?”
Guy 2: “yeah, he’s becoming a serious problem. It’s pretty clear Ryan is well regarded.”
