Term used, usually by a male, to indicate that he would be able to pleasure a certain female with a big booty, from the behind. That he would be able to "reach" it from behind despite the big butt.
GUY1 : "Damn did you just see that pretty girl with the big booty walk by?"

GUY2 : "Yeah i saw her. . . I'd reach that"
