a plastic bottle with the end cut off, filled with dryer sheets, and covered with a thick sock; is used to smoke grass when you dont wanna get caught, cause it hides the smell
"i dunno about smoking here, someone might smell it."
"oh don't worry, we'll just use the sploof, and the room will smell dryer sheet-fresh!"
When one exhales smoke into another fellow's rectum in order to disguise the odor. Much like a regular sploof but for the small cost of nothing.
Example:
'Smoking in the school bathroom'
Robert - OH SHIT, the principal is coming, quickly put your lips around my asshole and perform the poor man's sploof!
'Jonny exhales the dank smoke into the anal cavity of Robert'
Jonny - Thanks Robert, you saved us both. Also, no homo tho.
Robert - Yeah that was close, no homo hehe..
