The kind of flexing that many skinny, toned people do. The flex shows definitions within the muscle, but no real bulk. eg. the chest may look defined and expanded, but no bulk/beefyness to it much like how Bruce Lee flexs in his movies (but is still a beast)
HAHAHA! You really expect me to be scared of that Bruce Lee flex?
