Rhymes with "Collision"

Now I must go prepare for the weekend. I dare not say too much of it, save only that it involves me, four other men, and a lot of sweat. If you're in the camp of my well-wishers, then wish me well. If you're not, I hope your mom gets the herpes. I'll make some sort of report on it next week. Until then, I gotta go stretch out.
