Get the flying in a airplane mug.
when Kristen is drunk, you make up some sexually connotated gibberish and tell her it exists. And if she questions it, you say, "It does! Look it up on Urban Dictionary!" Oh yeah, it's also when 20 guys spray themselves with hair spray, light their genitals on fire, and procede to have crazy sex with one woman.
"OMFG! That hoard of savage, blood thirsty highwaymen were totally flying the airplane last night!"
