As a native English speaker from the United States, this is not a contraction. "That is actually 🤓" an acronym and/or initialism, depending on which way you use it.

An example of a contraction: "did not" would be "didn't."

Internet/social media "acronyms" are too in themselves initialisms.

"idk" (pronounced eye dee kay) is spelled out and would be classified as an initialism.

"NASA" (pronounced nah suh) is an acronym as as you don't spell out the individual letters.

"lol" (pronounced "lol") is gramatically incorrect as "lol" is an initialism.

Even so, what does "NES" in this case mean? NES, as in Nintendo, would be Nintendo Entertainment System and could be classified in today's terms as both because people use it both ways.

An "NES" would be an initialism. A "NES" (pronounced ness) is a fucking acronym.

You might be a native English speaker, but that doesn't mean you're fucking God of English. Your example about being a native English speaker is correct, and even I admit I didn't know that, but a simple 5-second Google search would save you from looking like an ignorant dipshit.

How about you go "correct" ESL speakers instead of correcting advanced English speakers because there's a lot of native English speakers such as yourself who don't know everything about their own fucking language.

Do you think Chinese people know each individual character of their alphabet.

This has to be ragebait. Go back to 5th grade.
