I don't know how he's one of these

No one in modern culture refers to the term "friend" as whatever definition you found. It's generally implied by the general public that it's referring to the slang term.
Honestly, why you would see the term used in a condescending manner of fashion and wonder why it's not the slang term is beyond me.
Also, the term friend isn't necessarily a bundle of twigs, it can also be a bundle of chopped meat, iron bars, herbs or pretty much a bundle of anything.
