“The idea of” makes me think of someone who cannot actually explain the idea, so must use some comparable.

Perhaps this lexicon comes into play more often in sales, where there may be more play in the expectations of the parties. The questions I face most days are fairly definitive: “Is it plumb?” “What is the measurement?” “Is the wire hot?”

100% – “Yes, absolutely, we agree 100%.”

Perfect – “This is perfect!” or flat out “PERFECT.”

Kinda/kind of – “We just kinda wanted to show you how great it would look if…” This one is the worst and least professional. Definitely cringeworthy, although you could argue it makes us sound more conversational/relatable.
