In Ireland -a 'snake-
oil' salesman : a committed 'Yes'
man , no matter what the question or his previous views on that subject : a 'know-it-all' who
will plausibly convince you of how right he is , while he fumbles in his greasy till , professionally hiding the fact that he knows nothing about the issue in question .
Usually ends up in a political career !
Too many to mention - also too libellous to do so !
" That
fella up at the
bar , there - he should be able to fix
ya up . He's a wee bit of a gombeenman , but sure he's not the worst ... "
