(1) Blow: To form one’s lips into a circle and expel air at varying velocities, in order to possibly remove something unwanted from a surface
(2) Blowing a Kiss: Same as above except also holding one’s hand, palm up, under one’s chin and, after making a gentle kissing sound, (which is exceptionally difficult to define) aiming the imaginary act of affection toward its intended recipient, expedited by air expelled somewhat more urgently while also eliciting a receptive response
(3) Blow Up!: Besides destroying one another’s advanced civilizations with incendiary bombs and rockets dropped from airplanes, also means a sudden argument gone out of control with supervisor, fellow workers, one’s spouse, customer, or, on particularly bad days, all of them
(4) A Harsh Blow: To strike another’s body or intellectual concepts without mercy. Can also mean to undercut one’s self esteem and likely to stifle one’s advancement in an organization unless the perpetrator of the act is decapitated in reality and not just in one’s imagination
(5) Blow, as per Presidential candidate Barak Obama: Cocaine, which surprisingly, is an elective at major universities throughout the world
