To have so much of something that your attitude towards using/spending/loosing it is "fuck it". Even more than "buckets" of something. Sometimes spelled "fuckets" if the amount of fucks given is slightly larger than for fuckits
a plastic bottle bong, mainly used in west belfast slang. u “blip” a hole in the side near the bottom of the bottle, put a gauze on top and pack it, burn it and as the g is burning you drain the water out the blip hole. when there’s a little water left you shake it up and “hoof the fuckit” che harbinson smokes skeets btw.
