How it's used
While 勃起 is the standard biological and medical term for an erection, it is rarely used in casual conversation. Most people prefer the slang term 扯旗 when speaking informally among friends. Using 勃起 in a social setting can sound overly clinical or like you are reading from a textbook.
Examples
He got an erection immediately when he saw the pretty girl.
Do you know why one gets an erection in the morning?

Common mistake
Avoid using 勃起 in casual or flirtatious contexts, as it sounds like a formal medical diagnosis. Stick to the more common slang 扯旗 to sound natural.
