selective capability disorder Mug

Refers to a broad range of pseudo-maladies (where the person is merely faking/exaggerating a certain physical/emotional/mental infirmity/disability, like the infamous "selective deafness") that many lazy/selfish/uncaring people complain of, merely to get out of performing some undesirable task. These supposed maladies include: (1) selective stamina/fatigue disorder, whereby the "sufferer" instantly becomes a nearly-lifeless "limp rag" whenever anything resembling w-o-r-k is requested/suggested; he always seems to be perfectly able to jump robustly back up again, though, when some fun/pleasant activity is subsequently offered or suggested (2) selective phobia disorder, whereby the "sufferer" claims to have an intense fear/loathing of a certain aspect of the task at hand, again, usually to simply be relieved of having to participate in said task; he often seems to be able to placidly/confidently manage other similar-context activities just fine, however (3) selective allergy/medical-condition disorder, similar to #2, whereby someone claims to have a serious illness/infirmity that would prevent him from safely performing a less-than-pleasant task, yet he's perfectly okay with less arduous/boring tasks which involve the same types of substances/conditions (4) selective strength/health disorder, whereby someone claims to not be physically muscular/fit enough to perform a certain task, but yet he lifts weights, moves heavy loads in a hand-truck/wheelbarrow, etc. at other times
