This trope occurs when one character — the parent (or expecting parent) of a newborn baby — asks another character to name said baby. It is implied that whatever name is chosen, it will be final.
For this trope to be in effect, the parent must relinquish their right to choose a name for their own child — which is something parents would not normally do in most Real Life cultures. A key ingredient is the implied (or outright stated) pact with another character, handing over the choice of name to that character for whatever reason. The parent may or may not eventually back out of that pact after learning which name has been chosen - but the trope still applies as long as that parent did in fact relinquish the right to choose, at any point.
The trope does not apply if the parent is asking a friend to come up with suggestions for names. It also does not apply if one parent is asking the other parent (or their own significant other) to name the child.
A variant of this trope occurs when the child-naming "pact" is made with fate, rather than with another character. This includes leaving it to random chance (such as casting lots), or more commonly when the parent promises to name a child after someone else whose name they don't yet know.
When this trope is played straight, it is usually done to show how awesome a character is, because the parent respects them so much (or owes them so much gratitude) that they will trust them to select a good name. In this case, the name will usually be selected on the spot and will be a proper and inspiring name. The child may also be named after another, beloved character who had recently died.
When the trope is subverted, of course, the selected name could be completely idiotic. At this point, the parent may or may not renege on the unwritten agreement and decide to withdraw the request retroactively.
The resulting name might fit any number of tropes on the Naming Conventions page. It will commonly result in Dead Guy Junior. Other options include Embarrassing First Name, Named After Someone Famous, or a Line-of-Sight Name.
Compare Last-Minute Baby Naming, where the parents do decide on their own, but almost without any forethought, potentially leading to similar results.

He picked what he claimed was a perfectly fine and wonderful name: Pantyhose Taro. And thus was created yet another vengeful rival for Ranma to deal with.

Poorchick ("Moocow" Poorchick for short), King My God He's Heavy the First, and Princess Esmeralda Margaret Note Spelling of Lancre.
