To get “stuck” means to get stabbed. Prodigy uses this as a metaphor to convey how the authenticity of their music hits individuals. “Stuck” may also be a substitute for “hooked"—they keep listeners coming back for more music from The Infamous Mobb Deep.

In Prodigy’s autobiography, My Infamous Life he explains where the moniker of The Infamous originated from:

We decided to call the album The Infamous. Yamit (Yambo) from Hav’s block gave us the name; he had “The Most Infamous” tattooed on his biceps in black ink. We were already Mobb Deep, but he dubbed us The Infamous Mobb Deep.

This has gone on to be one of the most iconic opening lines in hip-hop history.

“Wanted me on his songs” also refers to a poignant moment as to why the Jay vs Nas beef happened. The story goes (as told by Nas) that Jay wanted Nas on his 1st album, but Nas either was unable or unwilling.

Jay supposedly held a grudge regarding this for years and knew although he had higher sales, Nas still had the street cred and respect in regards to whom was the better lyricist, so he sought to lyrically assassinate Nas.

And at age six, he learned to do wheelies!

From Vibe (2003):

I was four years old but I remember that morning clearly. As my mom left for work, she told me to wait till she got home to practice riding my bike. My uncle had promised to put training wheels on the second bike I’d received from my cousin, but he hadn’t gotten around to it. Me being the younger of four kids, I was determined to be independent and not spoiled (Although my family will tell you that I am the latter.) I took the bike outside, and from 10 a.m. to 5pm. taught myself how to ride without training wheels. Because I was so small my whole block in Brooklyn was watching in amazement. It was my first feeling of being famous.

And from O Magazine in 2009:

I was too short to reach the pedals, so I put my legs through the V of the frame. I was famous. The little kid who could ride the ten-speed.

When one’s trigger finger is itchy, it means that the person is ready and willing to shoot at any cost. He really does not care about the consequences.

In one documentary, Fat Joe said that Pun used to actually shoot his gun on many occasions.

Rakim tells us that people are fiending for his lyrics so much that even the rhymes that he’s thrown away, like ancient artifacts, are being looked for by researchers. His rhymes are so lethal and complex that scientists still can’t seem to figure it out
