is a universal slang term for describing something, or naming an unknown item, or a body part... no actual item is a dripclatch, but the word does hold a vulgar undertone
that dumbass just got kicked square in the dripclatch!!
A manipulative tactic/method used in order to successfully lie claiming you only have the knowledge of what the truth is about the accusations of your actions (which in this case, the manipulator always claims the accusation is always false.) typically in a condescending manner, used to make the other feel smaller in terms of knowledge.
“Only I know I didn’t do that thing, but none of you will accept the truth no matter what I say”
