Holds the world record for the worlds largest penis. Looks like a mix of Patrick Swayze and Chuck Norris, with the skills of both. Goes by many nicknames, from BSL (Back-Seat Lover), to Skilleon (because he's so skilled). Pronounced like; Kill-E-An, or Kill-Leeanne, because thats how immense he is. He's a guys guy, and a ladies guy at the same time. Cillean, is the definiton of amazing.
Awh man, did you see Tom earlier? He was totally being Cillean!
