Lucy x Brock (Azami x Takeshi) and my OC kids for them feeling awkward and embarrassed by their lovey-dovey parents (they use cringy-cute pet names like "My little Geo Dude" and "My Serpen-Queen":
Jenny "Jen" (Hiriko), both names meaning generous/fair, and
Cody (Daisuke), both names meaning helpful.
Side note: Cody uses Ground-types and Jen uses Poison-types.
