A punch in the face

threat actor = someone who wants to punch you in the face
threat = the punch being thrown
vulnerability = your inability to defend against the punch
risk = the likelihood of getting punched in the face
acceptable risk = your willingness to be punched in the face

risk management = your ability to see the punch coming
