The Greek verb drassomai means to grasp or seize — often with the connotation of catching someone in the act or trapping them. In classical Greek it is used of catching fish or animals. In the New Testament it appears in 1 Corinthians 3:19 in a citation from Job.
Paul quotes Job 5:13 ('He catches (drassomai) the wise in their craftiness') to demonstrate that human wisdom — even at its most sophisticated — is unable to comprehend or contain God. The wise who build their systems of thought independent of God will find themselves caught in their own cleverness. This humbles all pretension to autonomous wisdom and points to Christ as 'the wisdom of God.'
