Researching heraldry and a few other symbols and keep running into “mullet” which is described usually as a pierced star. The following from Wikipedia:

In heraldry, the term star may refer to any star-shaped charge with any number of rays, which may appear straight or wavy, and may or may not be pierced. While there has been much confusion between the two due to their similar shape, a star with straight-sided rays is usually called a mullet while one with wavy rays is usually called an estoile.[1]

While a mullet may have any number of points, it is presumed to have five unless otherwise specified in the blazon, and pierced mullets are common; estoiles, however, are presumed to have six rays and (as of 1909) had not been found pierced.[1] In Scottish heraldry, an estoile is the same as in English heraldry, but it has been said that mullet refers only to a mullet pierced (also called a spur revel), while one that is not pierced is called a star.[1]

Of course my brain is stuck on star vs weird haircut. So I look it up in the dictionary to see what the deal is:

mullet 1 |?m?l?t|
noun
1 a chiefly marine fish that is widely caught for food.
[Families Mullidae (see red mullet) and Mugilidae (see gray mullet) .]
2 a hairstyle in which the hair is cut short at the front and sides and left long in back.
ORIGIN
late Middle English: from Old French mulet, diminutive of Latin mullus ‘red mullet,’ from Greek mullos. The origin of sense two is unknown but may be related to the fish.
mullet 2 |?m?l?t|
noun
Heraldry
a star with five (or more) straight-edged points or rays, as a charge or a mark of cadency for a third son.
ORIGIN
late Middle English: from Old French molette ‘rowel,’ diminutive of meule ‘millstone,’ from Latin mola ‘grindstone.’

Totally get the connection between millstones and starry depictions but the haircut? Still chewing on it.
