(n.) To beat up or assault someone who's indebted to a beating.
To 'file taxes' is to seek revenge from a previous situation or issue. Although the phrase can be used to describe a simple assault, it's more effective if used to replace the phrase, "I owe someone a fight."
"I'll be right back guys, gotta filing my taxes real quick."
