Bacterial Trapping
'Pathological' (from the word pathology) is a word related to 'obsession', derived from the word 'pathos' (meaning : suffering), and is usually used in context of mental illnesses. So no, I don't think it means Bacterial Trapping... More like Obsessive Trapping.
In other words, it'll most likely be a story involving a batshit seme who has a thought-out, long-term plan of eventually trapping the uke in an obsessive and potentially unhealthy relationship.
Ooo..I never knew the meaning behind the word...thaanks for the explanation.
Indeed he is adorable
