Loving someone so much that you hate them with the same instensity because you're afraid of rejection so you cover up your true feelings with the opposite.
Helga: Arnold! What a do-goody geek, how I loathe him... and yet... (sillymusic plays and she starts blabbing some poetry that she wrote about him)
Helga Pataki syndrome
In BTS song Mic Drop ft. Desiigner, the English part says "Did you see my bag? Do you see my bag? It's hella trophies and it's hella thick". They are referring that since they work hard their bag contain lots of trophies and it's heavy (thick). Since the original version is in Korean, when they sang that part in English it was funny so many people made it into a inside joke.
When a person does what Helga does to Arnold on the tv show “Hey Arnold."
When a girl or guy says nasty hurtful things to someone; but the person that is saying the nasty things really likes the person that he/she is bullying.
“Hey maybe that girl has the Helga Pataki Syndrome.”
