Respectfully, I disagree. To my mind, a "clickbait" title includes purposely omitting information for the purposes of getting you to click.
If this were a newspaper headline, it would've been "Man discovers mummified remains in deceased mother's freezer", because the purpose of the headline is to convey as much information as possible, succinctly. But the "clickbait" article intentionally omits what is in the freezer in the hopes of getting you to click to find out.
