Grass the top for me.
Whip the top for me (to get it to spin on its end).
Irisg 'Greas' - a turn (at a game) and 'Greasaim' - I beat, I strike, hence to beat the top with the lash of the whip. (Dinneen) and 'Gres' - an attack, a hostile encounter. 'Na tr√≠ fhuargres - of the three cold strokes'. (Byrne)
