When a guy "beats up" the pussy.. or "knocks the bottom outta the pussy".. in other words.. knows how to hit it right
"B's gonna beat it up this weekend"
referring to sex.. to also beat it up.. when the sex is so damn good..It feels like the bottom is gettin knocked out the pussy. preferrably with a huge dick.
