1.
n. the blonde whiteboy playa from Saved By The Bell. That dude was crazy!
v. I guess it means a type of 80's guitar solo, according to the cat above me. Either or random term, or derived from the fact the Saved by the Bell was around in the 80s and early 90's

3.
To be talking on a larger than normal cell phone, as Zack hauled around his cool "Cellular phone" during Saved By The Bell
When you see somebody on a cell phone that might be an older model, not 80's per se, but maybe something late 90's or early 2000's that's bigger than the phones that are "in". "That's so Zack Morris style".
