Pissing in the punch bowl is an analogy for one of the ways that non-entities attempt to garner attention for themselves at a social gathering. Uncivilized behavior, but it does draw attention to themselves.

Which is what you guys are obviusly after. Not content to discuss things rationally (or not having the intelligence to do so), you feel you need to name-call and insult. Are you sure that being regarded as an idiot and a boor is the kind of attention you really want?

Grow up.
