look up any word, like hipster:
 
1.
1:The part of its body a bacteria uses to move
2:The few long strands of hair left behind when your hair is cut by a trainee hairdresser or a family member.These rogue hairs resemble the flagellum of a bacteria. Must be in a clump with several hairs. Most prominent when combined with a bowl cut.These hairs should be tugged when the flagellum wearer is least expecting it. Found on guys and shaven headed lesbians.
Example 1:What interesting flagellum on that paramecium
Example 2:
Harry: hey guys!
Oliver,Matt and Nathan:so your sister renewed your bowl cut
Harry: yeh...
Oliver,Matt and Nathan:wats that on tha back of your head?
Harry:cant see..
Oliver,Matt and Nathan: AHHH!! ITS FLAGELLUM!!!!
