acting different 

Acting different really became highly popularized in 2019 with many twitch streamers using the word. But the origin was came from TSM_Hamlinz when his sister KayB was acting weird or different than the norm or the usual.

different strokes for different folks 

An expression meaning that everyone has their own way of doing things or approaching life. Often said in disagreement with how someone else has done things, but can also be said in a neutral or even positive fashion.

(rolling eyes) "He proposed to Susie through a casual email?!? Well, I guess different strokes for different folks."

Diggernick 

A somewhat witty way to avoid banhammers in online games yet still be perceived as a coolkid.

Mainly used in World of Warcraft where it is particularly hard to use and maintain an offensive name.

I was forced to namechange after exactly 32 days. It was fun while it lasted.

Diggernick says: HI guise!
Arthasthekingslayer says: Oh my lord, reported!
Diggernick says: where the white women at?

completely different level of swearing 

Used on those from a different country than you when dealing with and trying to understand their slang and accents.

"So I tell the swamp donkey to sock it before I give her a trunky in the tradesman's entrance and have her lick me yardballs!" ~Cecil

"Wow. You guys are on like a completely different level of swearing over here." ~Cooper, EuroTrip

Different Strokes Syndrome 

A book, television show or movie which seemed to be awesome when seen as a child but turn out to be unbearably shitty as an adult.

1. I tried to watch Voltron the other day. What a terrible show! I can't believe we watched that shit back in the day. Talk about Different Strokes Syndrome.

2. Jonathan Livingston Seagull gave me a total "I'm special" hard-on when I was 13. Due to Different Strokes Syndrome, I couldn't make it through the first chapter as an adult.
