In video games, an annoying-to-deal-with way to play against others in a combat-oriented/fighting game in which a player uses the terrain to their advantage, for example jumping on platforms to gain the high ground.

It isn't really "abuse", just the USE of terrain, but due to how annoying and unfair it is, people call it abuse.
Timmy: No fair! You terrain abused while using Ryu!!
James: DNC, you're the Chun-Li spamming Kikoken all game.

Get the terrain abuse mug.
When mods of a Discord server troll people in a way that is technically not against the rules.
Example 1:
> "Jab just gave me the 'go to ultrakill land' role, now I can't talk except in the #ultrakill channel!"
> "It's legal mod abuse so you can't complain about it."

Example 2:
> "Why do muted users get locked out of the server but can talk in that one channel?"
> "It's so mods and other people can make fun of them, it's legal mod abuse."

Example 3:
> "my nick has been changed to 'short people fucker' what the hell"

"i can't change it either"
> "legal mod abuse moment"
