Translation of "drseti" into English

Ves moj obraz drsi navzdol, ko neki izčrpani mlečni žele.

My whole face is sort of sliding downwards, like a rather exhausted blancmange.

Pusti drseti, samo nekaj bi dodal, to je bil osupljiv udarec.

Let it slip, but may I say, that was a stupendous shot.

V čarobnem vrtu pojeta, da sledita toku do izvira tako, da drsita po vodi.

In a magical garden, they sing how they follow the stream to its source gliding over the water.
