An example:
Nina: I saw Hippo Fart flirt with you.
Biba: yeah it was scary! She touched my shoulder. 😟

Huge sturdy packing-cases specially designed for humanely shipping large water-loving herbivores. Invented by the famous ancient philosopher.
Too bad Hippocrates wasn't born more recently, or his animal-transporting invention would have been much easier to create --- he could have just lined a number of modern large metal shipping-containers with foam-rubber, added fresh-air vents and some form of toilet-fixture, and voila! --- hippo crates.

Like hippo (from hypocrite), but also with a tiny body part. A "big mouth hippo" is a person who says something is wrong one day but then goes and does that exact same thing or has already done it in the past. Calling someone a tiny hippo is also making reference to their penis or if they are a women, their ass. So big mouth, small dick. Or big mouth, small ass (or tight arse - vulgar form). It is sometimes used to refer to a gay person who talks hypocritically, normally a bottom/submissive in the relationship.
