A nickname for the head of your penis when you pull out of a women on her period. The tip of your dick covered in blood resembles the orange star "Aldebaren".
Aldebaran is the brightest star in the constellation Taurus and is known as the "Eye of Taurus." The name "Aldebaran" is Arabic, which means "The Follower" because it appears to follow the Hyades star cluster that forms the head of the bull. It is an orange giant star measured to be about 65 light-years from the Sun in the zodiac constellation. Its magnitude is -2. 1 and its surface temperature is 3,910 K.
Aldebaran describes a person with a disfigured face. Add glasses to the face and the person will appear to look like a clown, remove the glasses and they look quite wrong.
Can be shortened to Alde, because everybody just wants to fucking shorten things nowadays
