A Blacktop Slurper can be someone who gives a blowjob to someone either during recess or P.E. But it also can be defined as pulling off to the side of the road and having your dick sucked.
"Hey Joey guess what happened at recess yesterday?"
"No way did you get a Blacktop Slurper!"
"Hell yeah I did Joey!"
"You are a legend man"
