look up any word, like sex:
 
1.
Feelings of desire for a person who is not particularly attractive but just happens to be the most attractive in the room at that point in time. Often occurs during long boring classes or lectures.

Sufferers usually come to a realisation that the subject of their lust is far less interesting if they ever see them in a different context.
"I thought Joey in my Linguistics class was really hot, but when I saw them in the supermarket I realised it was just a bad case of situational lust"
