An amazing hacker who made many applets, and reinvented hacking the battle.net matrix, and also researched the uses of the MSN cookies which later led to the capture of Hotmail accounts. Also goes under the name of "SeptoiD2" or "SeP2" Also "Septoid-2".
Suddenly your Battle.net Game Crashes, and you find your account's password changed, and your computer locked down. Sep's at it again... *sigh*

Get the Seiko mug.Alternate title for millimeter, named after the size of a certain Seilo's reproductive organ. The use of the word Seilo began in 2004 when a small, short and skinny boy was born. He was hated by everyone in his early childhood and he had a hard time making friends in kinder garden.
When he was 6 he was accepted to special-ed school. At the special-ed school around the age of 16 the doctors realized his puberty was not starting any time soon and they had to start an testosterone treatment but they actually mixed up the testosterone with estrogen after 2 moths of treatment he started growing breasts and his reproductive organ started to withdraw. After 3 of treatment it was already too late and his parents started to notice some odd behavior like not being able to ride his motorcycle at all and always complaining about his not getting paid enough even thought he wasn't working. His parents took him to the doctor, but Seilo was complaining the whole way there about his dads driving and calling him a "virgin" because Seilo hadn't learned yet how babies are made.
The doctors could not help since he already looked like a childish woman and the doctors also said he has a "3 inch shrimp dick" after this the word Seilo began to spread around Europe and now it's a popular insult in over 46 countries.
Nowadays it's not certain knowledge if this Seilo person ever existed but you can find an exact replica of him in a game called "Genshin Impact" and the characters name is "Venti".
