- Adaptation Displacement: The only reason many younger people ever heard of Rick James' "Super Freak" was because of the lawsuit Rick James filed against MC Hammer for the use of the song's Epic Riff.
- Ear Worm: "U Can't Touch This" and "2 Legit 2 Quit"
- In the span of "2 Legit 2 Quit"'s six minutes, the words "too legit" are spoken a whopping 120 times, with the entire phrase "too legit to quit" appearing 57 times within that number. That's a certain recipe for Ear Worm whether you want the song to stick around in your mind or not.
- I'm Still Relevant, Dammit!: The Funky Headhunter, in which Hammer responded to the many shots taken at him by from the newly-popular Gangsta Rap school by basically saying, hey, I'm down with this Darker and Edgier thing, too. It sold, but it didn't impress the gangsta crowd one bit.
- Memetic Mutation: Stop! Hammertime. Over time, this meme went from being spoken to being seen, as Stop signs can still be seen to this day with "HAMMER TIME" stamped on there either as graffiti, as an embossing or as a bumper sticker.
- Moment Of Awesome: Best. Mashup. Ever.
- Never Live It Down: MC Hammer's name has become synonymous with bankruptcy and Conspicuous Consumption. From the TV series Leverage:
Parker: Who ripped out the toilets?
Hardison: This was an IRS foreclosure. I got it cheap.
Eliot: IRS doesn't take toilets.
Hardison: They do when they're solid gold. Heard this used to be MC Hammer's place. I guess you can touch this, with a SWAT team and a federal warrant.
- Padding: In addition to the constant sampling as opposed to rapping to original beats, the other criticism laid heavily on Hammer was the constant repetition of his songs' choruses. This usually happened as his music videos were very long, and the album versions usually matched that length as opposed to being trimmed. This is exceptionally noticeable in "2 Legit 2 Quit", in which the chorus of "Too legit, too legit to quit" is played over the final two and a half minutes of the song without any lyrics from Hammer; this is fine in the music video, where there's a ton of athlete cameos popping up in the meantime, but it can drone on for someone listening to the single on its own.
- Sampled Up: "U Can't Touch This" sampled the main riff from "Super Freak" by Rick James. At least James got some of the moola.
- Most of Hammer's songs relied on what could be... charitably... described as less than creative sampling choices. These included Prince's "When Doves Cry" for "Pray" and "Soft and Wet" for "She's Soft and Wet", The Chi-Lites' "Have You Seen Her?" for "Have You Seen Her?", The Jackson 5's "Dancing Machine" for "Dancin' Machine", Marvin Gaye's "Mercy Mercy Me (The Ecology)" for "Help the Children" (Ah-ha! You expected "Save the Children", didn't you?) and George Clinton's oft-sampled "Atomic Dog" for "Pumps and a Bump". No word on whether they got their own moola, though.
- Signature Song: "U Can't Touch This," although "Too Legit" is fondly remembered by fans as well.
- The latter is still played at every Oakland A's home game, complete with the hand gestures displayed on the scoreboard.
