I don't know if he picked it up in college playing for the SW (Oklahoma) State Teachers Bulldogs or while he was HFC at OU during WWII, but Dewey Luster's nickname was "Snorter."
Joe Washington's nickname was "Little Joe," but Barry Switzer called him "Smoke." As in "through a keyhole."
Greg Pruitt was "Hello-Goodbye."
DL Raymond Hamilton was "Sugar Bear."
Keith Jackson was (at least to some OU fans) "No Relation," alluding to the broadcaster.
Joe Don Looney didn't have a nickname, but his last name described him pretty well.
NG Granville Liggins was "Granny."
