「Using hands on fleshpot orifice」might just burn one's fingers as INJURED, MARRED, SCARRED, DAMAGED.
　Lower-right element is「cauldron, fleshpot」perhaps meaning here to gather around for a group activity, with an「orifice」above or on the cauldron as the place from which to extract seething hot meat, or, the literal orifices of a young service provider made available while bound and tied securely to a three-legged cauldron, meaning「member(s), group activity.」Perhaps the English expression regarding one's「member」as an organ of a human or animal body is related to this Chinese glyph, and「using hands on one's own member」reflects MISSING OUT DESPITE WANTING TO DO an activity within a group.
　「Use hands with a member」to toss a person out and excommunicate him or her from the further activities of the members' club. Means LOSING due to a MISTAKE, ERROR, or DAMAGE, a SLIP, FAILURE. Also depicting SCARS and MARS as perhaps the reason for disfellowshipping a former member, someone who, due to uncontrolled overexcitement, INJURED, MARRED, SCARRED, DAMAGED the「orifice on a fleshpot」and therefore diminished the experiences of other members who had been patiently waiting their turn in line but MISSED OUT DESPITE WANTING TO DO.
　「Using one's hands」with an「orifice of a fleshpot」may be what caused the INJURY, IMPAIRMENT perhaps because of a SLIP-UP due to dirty, untrimmed fingernails, with the point being emphasized here that there was no reason to use one's hands in the first place, since the subject was bound and tied anyway…WASTEFUL. Chinese references to sarcasm and derision may relate to a member who could use nothing but「hands on his or her member.」Perhaps「hand use on fleshpot orifice」was all that was possible due to a gravely infected condition…after LOSING A PART?
