To beer bong, or not to beer bong

My husband and I are not really big drinkers, however we do like a drunk night on the porch now and again. So as my husband was teaching me how to shotgun a beer and it exploded into my face, burning my eyes, he asked if we were to old for a beer bong. Never being a beer bonger myself, I did not know the answer, and consulted some friends via text message. The only reply that I got was "I dunno", which is for obvious reasons, not helpful. So my question is, what is the appropriate cut off age for having a beer bong? Does it depend based on your life circumstances, or is there an age? I think that we could pretend now and then that we are drunk college students, might be a fun little role play.
