In loco parentis goes loco:

On a University of Michigan Web site, “‘external water sports’ is described as a type of ‘safer sex.’” (The phrase has nothing to do with a swimming pool.) At Virginia Commonwealth University, “cross-dressing is called a ‘recreational activity.’ ” The sexual advice blog “Go Ask Alice,” sponsored by Columbia University, provides helpful hints to students on ménages à trois (“Nothing wrong with giving it a try, so long as you’re all practicing safer sex”), swing-club etiquette and phone sex (“Getting Started”).
