Lushover
Lady + crush + hangover = Lushover. A Lushover (n) is a word for when you spend time with or meet a woman and you really enjoy the time together, so much that you develop a mini crush. The next day you wake up and your head and maybe heart are full of thoughts of this person. However, this feeling typically goes away in a couple hours or a couple days. Nothing to worry about, no need to act on it necessarily. Note: If it's especially strong, say a couple months or years its more than a lushover.
