Ass-to-Mouth Resuscitation is the hilarious task of reviving somebody who is asleep or passed out by spreading ones naked butt cheeks and positioning it over a recipients mouth and farting into it. It is much better when witnessed by people who are trying to contain their laughter until the procedure has been successful. Compared to its more well known cousin 'mouth-to-mouth resuscitation', Ass-to-Mouth Resuscitation is an often thankless alternative, and if the recipient is woken by it, their response can range from aggressiveness, nausea and laughter, sometimes the recipient may experience all three of these symptoms. Ass-to-Mouth Resuscitation or 'ATM' as it's affectionately known can also be used to boost morale of those witnessing the said procedure, and the fond memories would never cease to bring tears of laughter to their eyes for years to come.
