1.When one plays "baseball" they are talking about how far you got to sex. Getting to first base meaning you just madeout with your boyfriend or girlfriend. Getting to second base is basically strip making out, or making out naked,as well as handjobs and finger. Geting to third base is head (blowjobs) and eating. Hitting a homerun is having sex.
Guy 1- "Dude, I hear you were playing baseball with Jane last night?"
Guy 2- "Yeah man! 3rd base man!"
Guy 1- "Damn man, you almost hit a homer?"
Guy 2- "Almost..."

Playing Mormon baseball refers to the extremely mild "sexual" acts that Mormons engage in with each other, such as, but not limited to:

Eye contact, light banter, holding hands (NO INTERLACING FINGERS! THAT'S FOR SLUTS AND WHORES), sitting next to each other in church, buying each other promise rings, making rice crispy squares, separated hugging, and, in extreme cases, aggressive spooning.
I could hear Elder Drew and Sharron playing Mormon baseball last night in the other room. I think they were watching 19 Kids and Counting on the couch together!
