poast

First sense is ancient; second sense probably first attested in c. early-2010s, but in common usage only as of the late 2010s. The spelling variant seems unexplained and may just be fanciful, or deliberately childish (compare memes like fren and groyper).

poast (plural poasts)

1. Obsolete form of post.
2. (humorous, Internet) A post on an internet site, especially associated with being "terminally online" or causing mischief, or other such tomfoolery.

Slang sense seems to often carry intense tongue-in-cheek connotations. Sometimes used plainly referring to the general "brand" of someone's content style.
