Heini means "fit" in Welsh. Welsh Heini's are fit, as in athletic and fit generally. They are bright and bouncy too, although given to drinking too much on occasion, and walking oddly when drunk and in heels. In essence, a floozy in a onesie.
Welsh Guy 1: W yli ma'r hogan yna yn heini (Eng: Ooo that girl's fit)
Welsh Guy 2: Ond mae hi'n cerdded fel y Grinch (Eng: Ye but she's walking like the Grinch)

A very cool girl who is an amazing friend. Heinis typically take in the weird introverts and collect them into their friend groups, they are kind and smart and everyone likes them.

The Americans and Canadians referred to Germans, especially German soldiers as "Heinies", from the pet form of the common German male proper name Heinrich.
In the film 1941 the Slim Pickens character calls a German Officer "Mr. Hynee Kraut!"
Heini is actually a common German slang word with a slight derogatory meaning similar to moron or idiot, but it could be of different origin.
