Last time i offered a girl a beer bong i was a junior in undergrad at Iowa (greatest football team in the world by the way). well this girl, Kristin, somehow took me up on the offer and found herself occupying my bedroom last that night. come to think of it, the damn woman took over my room for the next 1.5 years and continues to do so whenever she visits.
moral of the story = offering a beer bong might be the sweet thing that gets you where you ultimately want to go that evening; however, girls rarely mean it when they say "girls just want to have fun." they mean to say "i will blow you away and make you happy only to someday make you feel guilty and get suckered into doing everything for me, including my little 19 year old sister."
