Imbibing? He could fucking do it!
My friend Rich. A fellow who enjoyed a beer or 15.
He could be most eloquent and graceful in both his consumption of alcohol and the often ensuing expulsion of it.
A few of his efforts as examples -

There was the time we were all sitting around a table at the Shents (The Shenton Park Hotel - a now long gone, great, original music venue & our then local) after work one balmy summer evening.
Rich decides it's his shout by deciding to consume the last of the dregs of the jug. From the jug. But now there was a small problem - since we had spent much of the arvo playing "coins" & ibble-dibble and many elbows had been "pointed" Rich's way, his body had reached the point where some volume of fluid would have to be expelled in order to make some room for more. Rich calmly pushes back his chair from the table, leans forward and sends a carrot encrusted yawn to the technicolour gods, between his workboots.
Amidst a mixture of applause and sounds of revulsion Rich smilingly gets up and heads to the bar to to procure some more libations for the group.

Another time Rich & I were staggering home from a similar evening when he felt the pressing need to empty his bladder. Not one who wishes to be inconvenienced by the need to stop moving whilst urinating and despite my protestations Rich unzips himself, flops his dick out and while continuing to walk bow-leggedly, proceeds to piss. All over himself & his shoes. On the footpath. Aside a busy 4 lane highway. In a shopping district. On "late-night" shopping night.

If he was still around I think I'd probably break my hiatus from the demon drink and crack a bottle or 3 with him this arvo. For old times sake.

Please understand gentle reader that these events and many others happened in our late teens and early 20's when a young man's attention to bodily functions and social responsibility are not necessarily honed to the fine point that they hopefully become later on in life.

Cheers.
EDIT: tl;dr? - my friend spewed and pissed on himself whilst drunk in public (amongst other things).
