Basically, in my experience with Herpritams at least the one I know, are kinda annoying? Joking. They're very sweet and a good friend. Shy but a genius. If you're friends any Herpritams, be grateful of the fact they're not scared of you and that they enjoy you as a friend as well. (I can't guarantee they think of you like that, sorry)
Anyone who believes that an insensitive, insecure, and jealous git like Ron Weasley is good enough for a smart, intelligent, loyal, woman like Hermione Granger.
The term comes from Harry Potter fanfiction, where H/R ('heron') refers to Hermione/Ron shippers.
Herritage boy is an attracitve guy who may come across as a prep, they are have amazing hair that usually blonde but there are a few exeptions, they also dress really well and girls love them.
