Idiom of the Day (Slang)
“Full of Crap” (semi-derogatory)
“Full

of Shit” (derogatory)

Oh boy. Sometimes I have to teach you inappropriate language. I sincerely apologize if this is offensive to anyone.

Sometimes people say things that are completely unbelievable. Maybe it is a lie or an exaggeration. In response to your disbelief, you can tell them they are full of crap. (Or shit if you want to insult them.)

“A student told the class that he had 15 girlfriends. I told him that he was so full of crap that his eyes were brown.” 😂😂😂
