Eyeballing

Ivan was walking around, eyeballing us.

He weighed of one kilogram of vegetables by eyeballing it.

"Another term was 'eyeballing,' which meant viewing and gandering around, such as 'eyeballing into Napels.'"

When he did eventually return to work, those employees he'd identified as the ringleaders of the unionisation bid found themselves getting unexpectedly called into his office at odd hours of the day for intimidatory eyeballings.
