1. Affirmative; Yes.
2. I agreed with you from the start of that last sentence.
"These evil robots are really getting on my nerves lately."
"Oh, yeah, no, for sure. They've taken it too far with the probes."
This two-word term quickly describes the mindset of an entity who is as certain as possible with the obvious possible exception of being mistaken by reason of being human, all members of said species being prone to make mistakes.
The term is derived from the 19th century slogan of Ivory Soap, first sold in 1879 with the taglines "It Floats" and it's "99 and 44/100 Percent Pure."
The strangely precise figure was derived from independent laboratory tests conducted in 1881 that discovered that Ivory soap only contained 0.56% impurities. Impurities in this sense meaning anything other than fat or alkali, the basic content of most soap." So, qualifying any statement with the addition of the term "Ivory-sure" means being as sure as is humanly possible.
"Are you sure that your cousin won't spoil our little party?"
"Ivory-sure, friend. The party is on."
