A really bad pun stemming from the word "utterly" and used as an intensifier in conjunction with anything involving breastfeeding or mammaries. A reference to cow or other animal udders.
That woman just pulled out her boob at the dinner table, clamped her baby to it, and it just went sucking away -- it was "udderly" disgusting to those of us without crumb-snatchers of our own.

When someone or something is irrelevant to you or is acting like an ass shoe.Also could mean what someone is acting like then the word is used.
