Boxers hug each other during a fight primarily as a tactic called "clinching." This is not an affectionate hug but a strategic maneuver used for several reasons: to catch their breath, recover their wits when hurt, slow down the pace of the fight, tire or frustrate the opponent, avoid punches, regain control, and sometimes to land punches in close range. It can also be used to escape when trapped or when being outclassed. After a fight, boxers may hug each other to show respect for each other's skill and hard work. The clinch usually involves holding the opponent tightly with the arms, resting the forehead on their shoulder to minimize headbutts, and putting weight on them to gain a rest while forcing the opponent to work harder. Clinching temporarily breaks up the opponent's offensive rhythm and gives time to clear the head if stunned or tired. The referee typically breaks up clinches after a few seconds to keep the fight flowing. In summary, boxers hug or clinch to manage the physical toll of a long fight, control the tempo, protect themselves, and strategize against their opponent's attacks rather than as a sign of affection.
