The first time having sex with your girlfriend. You have meticulously planned every part of the event down to the most minute detail. It finally happens and it is executed with perfection, though your mind was hazy, and all you know is that it ended with a head shot.
I finally had sex with Trudie last night. It ended up being a Robert O'Neill, but it was great and I can't wait to do it again.

THe coolest teacher in the universe. So awesome that 1/3 of his class dressed as him on a friday. Sometimes he will give us goldfish. He is the greatest Social studies teacher. He always has his pocket constitution and volleyball rulebook.
