A Big Rapids sprinkler is when a girl gives you head, you cum in her mouth, and then she blows the cum back out all over your face. They are named for the types of girls you'll get in Big Rapids, MI, home of Ferris State University.
I thought I had just got the best head in my life from Becky until she stood up and gave me a Big Rapids sprinkler.
