A very sexy guy who co-starred on the hit youtube show "Is It A Good Idea to Microwave This?" The mere mention of his name can make women want to be impregnated with his babies. Every girl and the occasional male wants to have a Riley McIlwain if not then they haven't witness his totally awesomeness.
"Hey did you watch Riley McIlwain on youtube last night?"
"Yeah, I want to be impregnated with his children."
"Dude, you're a guy."
"...So..."
"Yeah, I want to be impregnated with his children."
"Dude, you're a guy."
"...So..."

Similar in nature to a Mexican Minute, it indicates a lack of urgency or a tendency to show up at ones own leisure, with little regard for others time.
Nick arranged a game of FIFA to start at 9:35pm, however didn't show up untl 9:50. The length of time that passed before he showed up is a McIlwain Minute.

A period of time falling between a Mexican Minute (about 5 minutes) and a Jones Minute (about half an hour).
Nick came up with the idea of meeting at the bar at 6:45, but he was a McIlwain Minute late, even though he lived a minute away.
