Get the A Henry mug.
A German or Irish name meaning "Hero" or "Ruler of the home". Henry's are some of the sweetest people once you get to know them. They are also great friends, as they stand up to those who mess with others and would gladly take a bullet for someone they love. Henry's like to mess around with others, especially if they feel close to you and they care about you deeply.

Most Henry's have a troubled past and seem to daze off at random times, reflecting on that past.

A super hot funny boy. Tends to deny his feelings for girls but you can tell who he likes by the gleam in his eye.

His smile is the cutest thing you will ever see and he has the most amazing body. One goddam look at him and girls would die. All girls basically wanna bang him

Girl2: I don't know, but look at that fuck worthy body
