avuncular:

1 : of or relating to an uncle
2 : suggestive of an uncle especially in kindliness or geniality

how to use in casual conversation:

"the kindly old man displayed an avuncular nature while distributing the poisoned candy"

not to be confused with:

vernaulcar

how is makes me feel:

i like it. MW did well today. the dictionary.com entry was esurient which was also an amazing entry, but i went with avuncular. why? because i have a bunch of uncles, most of whom i like quite a bit. just kidding uncle bob.

it also reminds me of walt. walt was a guy i used to work with. walt was a black man in his early 50's from south carolina who worked with a bunch of twenty somethings. walt was prone to saying things like 'dang ol' and 'well hot damn'. sometimes walt would preface things he said to me now 'now listen here my young partner'. i once made a joke about him getting his AARP card. he never let me forget it. anyways. we called him uncle walt. possibly for his warm spirit and kindly, helpful disposition but probably also for the amount of avuncular ball busting he would routinely unleash upon us. here's to uncle walt.
