When having intercourse on the beach you pull out, stick your schlong in the sand and then instantly stick it into your girls poop box. Warning this could cause multiple cuts on your wenie and sand in your girls anus.
Wow my weiner hurts really bad because i performed the sandy poop box on my girl.

Sandy Box refers to the unpleasant experience of getting sand inside female genitals.
Not sure what is wrong with Bill, he's acting like he's got a sandy box today (or ..acting like he has sand in his box...)
