Can a worse hand call this?

[moose47]

Typical nano-limit table. Lots of loose-passives. That said, this question isn't so much directed at this particular hand but at this general scenario at higher micro limits. On the river, the second I clicked bet I immidiately thought to myself, "Nobody with a worse hand can call this." So here I am looking for some input...
