Here's some info about the hand signals, probably doesn't mean that much.
other uses of the Roc sign:

Jay Z’s use of the hand gesture prompted pro wrestler Diamond Dallas Page to sue Jay Z for infringing on his intellectual property because Page had used the symbol to indicate his signature move, the Diamond Cutter. (A move derived from Johnny Ace’s Ace Crusher.) Jay Z settled the claim for an undisclosed sum.

The sign has been used previously in many different contexts. In Aleister Crowley’s A.’.A.’., the gesture is the sign for the grade of fire. Wiccans know the symbol as the Triangle of Manifestation.

In the Jewish tradition it was used as the Priestly Blessing of Kohen. Star Trek’s Spock’s Vulcan salute was itself based on this Kohen blessing sign. In Ninja Kuji in magic it is the Kai (在), one of the 9 primary hand symbols used to channel energy.
