I meant you usually snort/insufflate solids, not liquids, to my knowledge, but ~2-3 grams of solids is a LOT to inhale at one sitting.
Other thing: That could be my fault--over at a certain other forum of drugs, where I also delight with my whimsical yet piercing wit, some asshole kept referring to "boofing" as "plugging" and got his "booty bumps" confused too. Which confused me for way too long, causing me much embarrassment at Reddit later.
Anyway, my understanding:
"boofing" means inserting by needle-less syringe, a small amount of dissolved/suspended/emulsified drug into your rectum.
"plugging" means either a) greasing up your finger for direct digital delivery of drugs to your rectum;
or b) using a needle to inject dissolved/suspended/emulsified drug into a gelatin capsule, and digitally inserting that into your rectum.
In both cases for shrooms, you'd need to do an aqueous extraction.
For plugging subsection a) you'd be shoving an awful lot of shroomdust up your butthole; definitely not practical.
(An actual booty-bump is not a boof but more akin to plugging section a) with a substitution in delivery appendage (exclusive to kinked-out meth-heads (and oh, the things you can learn!, and never unsee)))
