I think this is a fairly common succulent that I've seen before, but I've pored over pictures on this and other sites and can't find anything that looks the same.
Comments for I feel like I should know this succulent!
This is a commonly grown plant - it's Echeveria 'Topsy Turvy'. You must be providing it with exactly the right conditions for it to bloom like that - three flower stalks!
They are often grown as succulent house plants, and add so much to a collection of other similar plants like Echeveria, x Graptoveria and Pachyphytum. These plants all need similar care, bright light, excellent drainage, and no contact which will rub off the pruinose or 'bloom' from the leaves (this is similar to what is on grapes or plums to protect them from intense sun).
