No way I'm taking home that hippo. She reeks of patchouli and probably hasn't shaved her bush since the 90s.

A really epic guy who can paddle like a mother fucker and make you the happiest person ever....a hippo's advice is the most valid advice someone could recieve. Someone that doesnt realize how good of a person he is. Doesnt realize how many people look up to him, and would do anything for him. A best friend, an older brother, life-long friend.
Danny is a hippo!

hippo is a nickname you give someone who is a complete hypocrite. they preech to you about something so uncool so intensly, and do that exact uncool thing. this nick works even better if they're starting to grow a double chin

Another word for hypocrite, as in some douchebong saying for example "You're bothering someone so why do you keep bothering them?" And they end up doing that like 5 seconds later.
