young, dumb and full of cum 

When one gets home from school and thinks about doing homework for math class, then goes to look up what does Calculus really mean on the internet, but then he remembers that extremely hot chick in class with the cheerleader outfit, that was giving him the I wanna fuck stare, while pulling up her skirt a little to reveal her perfect gams, and then he gets severely distracted by the gigundous amount of porn there is on the nets, and decides instead to spend the rest of the evening shooting a load off. Then after shooting off waterfalls of cum, passes out and completely forgets he even had any homework at all.

In other words it means fulfilling your inner animal need to release sperm, or thinking with your dick, instead of using your intellect to figure out things like math, in the thinking fucking part of the brain.

Math Teacher: "Ok everyone, turn in your homework, oh guess what we have a surprise test today!"
McFly: "Aw shit I spent the night looking at porn and beating off, cause Mary Jane Rottencrotch keeps giving me the fuck me eyes in her cheerleading uniform."
Biff: "Oh man well you're fucked. I guess you forgot to do MY homework too, man quit jerking off McFly."
Mary Jane Rottencrotch:"Were you thinking of me when you were spanking?"
McFly:"Dammit quit being so hot. Why can't I just do my homework instead of slapping the salami all the time?"
Math Teacher: "That's because you are young, dumb and full of cum."

let it cum 

"let it come" is what other guys shout when you say "I'm gonna cum" while another dude is sucking your dick.

Matt said "I'm gonna cum" before he blew his load into my mouth -- and another dude shouted "let it cum" !

buffalo cum 

Road construction term: The white petroleum based release agent applied to the steel forms for concrete curbing etc. to prevent the forms from adhering to the curing concrete when they are removed.

You better spray some of that buffalo cum on the forms or you'll never get them off without fucking up the curbing.
