fanfic100 challenge, Birth prompt (34 down, 66 to go) because it all could have started like this. Set in Season 2, teeny tiny spoiler (blink and you'll miss it) for GUP. Written because 
spaggel requested John and Rodney drunk and start doing stupid drunk things and then Rodney is all, "Yeah, well, you may be the BIGGEST SLUT EVER and have chicks all over you. but my dick is SO MUCH BIGGER and I bet I'm better at it too." And John is all, "whatever *talk to the hand*" and Rodney is all, "no no no, really. See?" And Rodney shows him and John is has to show his, and is all, "Yeah, well, it's not hard so this means NOTHING." and then Rodney gives him a hand job and makes john touch his dick too. And Rodney is still bigger and John is all, "uh, yeah, but, I'M SO MUCH BETTER THEN YOU WITH IT." And then Rodney proves him wrong. Rodney edged closer, snagging the bottle back for a quick drink before answering. “Enormous, as in, extraordinarily large,” he giggled again, “like my intellect now that I think about it. Enormous as in vast, immense, and no doubt bigger than yours.”
