"typical GTM answer from you, given your mrs has got you by the balls and there's no chance you're coming out!"
You ask a friend of they're coming out for a coffee tonight
and they say "yes", even though they know full well they're not coming because they're too lazy or not allowed. This is a GTM (gia ta matia) comment.
Just saying it to "save face" or to avoid heckling and retribution from peers, as their partner (wife/
girlfriend) probably won't let them go out. So they they're saying "just for the eyes", but don't mean it.
