turn someone's head
turn (one's) head
1. To avoid paying attention to something uncomfortable, undesirable, unsafe, or inconvenient. We all knew that what the board of directors was doing was wrong, but we all just turned our heads because we were still profiting from it. Everyone turned their heads when we raised concerns years ago, and look at what happened as a result!
2. To cause someone to suddenly become fixated or infatuated. She spent all summer exercising and changing her eating habits, and she turned everyone's heads when she came back to school that fall.
3. To cause someone to become arrogant, conceited, or self-important. He's a pretty mediocre writer, but getting published in that literary journal seems to have turned his head.
