Onii-chan

A strikingly sexy male friend, who all girls fawn over. A word used in replacement for the male friend's name whom you drool over so dearly. In Japanese, Onii-chan means older brother, and is a title of respect and in some cases, resentment. Onii-chan is a word commonly used during weaboos climaxing over hot characters in their favourite anime

Hands off! Lincoln is my Onii-chan!
