To wipe something means to clean it with a cloth or other material, usually to remove dirt, water, or another substance that's covering it.
When we use the word 'wipe', it often happens in everyday situations. For example, you might be cleaning up after eating and grab some paper towels to wipe your hands before washing them under running water. You can also wipe a table or countertop with a cloth after someone spills something on it. Sometimes, people will even tell their kids to wipe down the toys after playtime so they don't get all dirty.
To move an object over, maintaining contact, with the intention of removing some substance from the surface. (Compare rub.)
Example: I wiped the sweat from my brow with the back of my hand.
To have all members of a party die in a single campaign, event, or battle; to be wiped out.
Example: If you try to fight that boss underprepared, you're definitely gonna wipe.
