Ain't nothin but a peanut
A phrase created by Ronnie Coleman which is used by him and other bodybuilders/power lifters to get pumped up before lifting a set. This is used to convince the lifter that the weight is light and he can rep it out no problem.
"Hey man, you ready to get it crunk?"
"Man it ain't nothin but a peanut!!"
"Man it ain't nothin but a peanut!!"
