"Slip with their eyes" meaning

[Amra94]

Does anybody know what slip with their eyes could mean in 6851 And indeed, those who disbelieve would almost make you slip with their eyes when they hear the reminder, and they say, "Indeed, he is possessed."

Evil eye?

[good_logic]

What about this?
6851
Those who disbelieved show their ridicule(about the messenger) in their eyes when they hear the message and say, "He is crazy!"

Every messenger has countless opposition of people showing ridicule in their eyes and speech that turns into hatred to the point of having some killed!
Most of the people who believe in a messenger ridicule the new messenger regardless of the truth, Their favorite messenger as far as they are concerned is the only worthy messengerand the last messenger.
GOD bless you.
Peace.
