Man I did that by accident in the back seat of a 2 door cavalier in high school. I went out on a date with my buddy and his girlfriend. His gf was driving (her car) i was In the back seat with my date. And was just chatting and flirting with her and started playing with her keys and asked what is this? Before she could answer I sprayed the $h!t. Omg it was horrible. We couldn't get out of the car cause we was on the interstate by the time we got the car off the road everyone was crying and bubbling Haha. Needless to say I didnt get a second date!! Haha
