An in-breeding between stagger, wag(ger), sag(ger) and if you wish to make a semordnilap out of the latter then you will all be due for the complementary (hot) gas that no doubt is juxtaposed with all of the self-congratulorly hot air that comes out of it's opposite and sometimes apposite top end.
No dumb arses who think they have swag. Coz U don't!!!
