This sentence is correct with what. The reason I say that is because …
“That reptile” - meaning perhaps a bad person
“what you call a son” - defining who it is (son of someone), also sounding sarcastic
“has made me appear in a sleazy publication” - so this person has done something mean
Other examples I found: “that’s what you call a son” / “Mom, is that what you call a son?”
How very kind of you, Andrea. I really appreciate your answer. I hope everything is well with you too. We must talk soon. Meanwhile, keep safe and give my regards to your husband and your daughters.
You’re right about the bad person and the person being sarcastic. Here’s the url, have fun:
