The 90's Show has more or less identical humor to the 70's Show. When was the last time you actually watched That 70s Show? .....right, that's the problem: the original had its moment but it's pretty stale.
And, as stated, there's really nothing notable about the 90s you could see people using and feel terribly nostalgic about.
Pronounced "Whup-pot". Say it. Use it.
