Madge to Guy -- You're a Retard

Madonna didn't waste any time throttling her now-estranged guy Guy Ritchie at her gig in Boston last night.

Without naming names, she intro'd her song "Miles Away" by saying it was for the "emotionally retarded ... You might know a few people who fall into that category ... God knows I do."

But it could be Madge who ends up looking like a bigger 'tard because she didn't sign a prenup -- and could have to shell out as much as $200 mil to Guy, even though he's being quoted in one Brit tab saying he doesn't want a penny of her cash.

Right ... and Heather Mills isn't a golddigger.
