Heyo, Bo knows this, (What?) and Bo knows that (What?)
But Bo don't know jack, cause Bo can't rap

from A Tribe Called Quest (Ft. Leaders of the New School) – Scenario Lyrics on Rap Genius

Meaning

Refers to early 90’s Nike campaign featuring Bo Jackson and the slogan “Bo Knows.” Jackson was a multisport athlete and Nike used him to promote their crosstrainers.

It’s also a little bit of word play. Since Phife is saying he doesn’t know anything, he uses his last name to contribute with it “ Bo don’t know Jack,” meaning Jackson.
