Taxi Slogans

Many taxis in Monrovia have a slogan painted on the back bumper. Sometimes it's just the name of the driver, but usually it's a message. As a foreigner, I often wonder what the slogans mean, even though they're written in English. Just on the way to work this AM, I wrote down these:

SYSTEM BIRD
50-50
GOD'S TIME IS THE BEST
SHINE YOUR EYES [means "beware" or "watch out"]
NIMBA BOY BACK IN TOWN
GOD DECISION STAND
CITY BOY
GOD IS IN CONTROL*
NO FOOD FOR LAZY MAN
THE COUNTRY RUNNING
FAT BOY
CKA SLASH [meaning "commonly known as"]
