Examples:

Denis expertedly gestured cross-wise over his forearm. Bruno's movies-based apperception of the vessel-knifing problematics, however, was that veins should be cut through on the wrist. (Context: Two naive boys want to establish a mutual bond by blood brotherhood but do not know how to perform a proper blood handshake.
