To have a crush on someone you see daily in the hallway/ at school but they don't have any classes with you or haven't even had a conversation with you; you have no means to communicate/ you try to but fail
"Omg! My hallway crush is coming this way! Smile, and pretend you're laughing i'll make eye contact!"
