an individual with the ability to trap you in conversation against your will. the longer you stay the more they digress as you sink slowly into their rambling world. struggling only brings up more conversation topics and thus exacerbates the problem. the whole time you are filled with dread because you know at the end you may be asked to commit to a future event. like coffee, or a month holiday.
any situation in which one is trapped in conversation against their will. the conversation is one sided usually punctuated by the infrequent 'yep' in the hope agreeing will end the conversation sooner. the trapper is the quicksand conversationalist.
