Guider Couple

A couple seen with arms around their significant partners while walking, creating the illusion that they are guiding each other as they walk. Usually seen at the beginning of a relationship, guider couples seem to die down as the relationship ages.

"Look at that guider couple. Can't they get to a destination without help?"

Guidevantage 

When, in a game of Dungeons and Dragons, one player has to perform a certain action (like a Rogue unlocking a locked chest), and two players help them to maximize chances of success (one by giving them Advantage, and the other using Guidance on them).

I'll open the lock, guys, give me Guidevantage.
