If it was not allowed to use bad language here then I doubt the forum would be of much use . I'm sorry, please forgive my poor humour.Originally Posted by Stella82
The word you quote is spelt "saggable", and it is an adjective referring to the fact that women's breasts tend to lose their elasticity with age, and so relax towards the ground ('sag'). This is considered to be an insult, particularly when directed towards a woman.
A'git' is a derogatory slang term, which can be applied to either sex. It is most often used in the form 'old git', meaning an elderly person, and used by a younger person who has been annoyed by an elderly person in some fashion. In fact, a popular BBC Radio host called Terry leverages this usage by referring to his listeners affectionately as TOGs (Terry's Old Gits) in an ironic sense.
However, 'git' is so ubiquitous a slang term now that it may be used to describe anyone. It is also only a mildly offensive term in British English, and so may be used 'safely' in unknown company. Conversely, for example, only an ignorant fool or a confirmed racist would use the term 'nig***' outside of their 'comfort zone'.
So the answer to your question is that the woman was denigrating your colleague by suggesting she had loose, unmuscular breasts. The 'git' suffix is just a convenient epithet to attach, probably chosen because it is relatively inoffensive in our culture.
This is often a difficult point to convey to EFL learners because it is a question of cultural difference. In many countries in the Far East, for example, the idea of ridiculing one's colleagues in any way would be anathema. In the UK, and to a lesser extent in the USA, such 'teasing' is not only normal, but expected.
