A girl/lady with overweight legs. Irish slang alluding to the fact that Mullingar in County Westmeath is noted for is good beef (a heifer is a cow who has not had a calf yet).
Male 1: Who did Mike go home with last night?
Male 2: I didn't recognise her, but i'll tell ya, she had beef to the heels, like a Mullingar heifer.
to talk mad sh** or start an argument or fight. like instead of saying, 'she wanna fight you!' you use, "oh hell naw! she tryna bring beef to the platter!"
Girl1:So yesterday i was talking with Andrew and then i noticed Lacey was giving me a dirty look.
Girl2:OMG girl! Lacey tryna bring beef to the platter!
