Slagging is a term used to describe a kind of harsher form of teasing. While this may seem like an insult to some, to the Irish, it's considered a behavior that shows affection or bonding, and, in some cases, is even used as a compliment.

The addition of superfluous material (SLAG) to a “news story”, the addition of which is designed to prejudice the recipient’s response to “news”, thus guaranteeing that the recipient will “comprehend” and “understand” the story correctly—in the manipulative lights of those responsible for said slagging. NPR and Clearchannel are equally guilty but from opposite ends of the political spectrum since both “clue” the listener about the “correct” response to the story moreso than giving out raw data for the listener to evaluate.

I.E. the application of Bernays-esque “spin doctoring” to influence public perception while pretending to the objectivity of reporting. Political Correctness and Neo-Con Righteousness are equally guilty of the abuse. So named from “SLAG”, the impurities burned and refined out of raw material in metal working.
Neocon slagging: The Palestinian "terrorists" objected to Israel's bombing of food supplies in Gaza.

PC slagging: The election of a "black" president is a mile stone in race relation.

I find slagging very helpful to get things done. I simply say "It's so sexy when you take out the recycling without being asked" or "When you put away the nails and screws instead of leaving them on the armoire it makes me want to nail and screw"
