low trumpet 

an unpleasant or rude person. Especially someone who doesn't realize just how obnoxious they truly are.

See that Brown student over there? The one telling everyone how he spent a semester at Harvard and how number theory is pretty much the best thing ever? He's a low trumpet if I ever saw one.
