"Ugandan discussions" is a euphemism for sex coined during the early 1970s by the satirical British magazine "
Private Eye".
The basis of the term arose at a party in London hosted by
Neal Ascherson at which Irish moralist and journalist Mary Kenny, during her early, wild phase, spent some time upstairs with a former Ugandan government minister. On rejoining the other guests, Kenny explained their absence by saying they were "upstairs discussing
Uganda".
— Where are they?
— I believe they
slipped away for some private Ugandan discussions.
— She looks like she was dragged through a
hedge backwards!
— She was upstairs discussing the situation in
Uganda, allegedly.
