Sweet Brains

1. Penis being sucked beyond recognition.

2. Being able to put the penis and balls in an entire mouth.

3. Oral Sex so good, you didn't even want the pussy afterwards then made a sandwich and went straight to sleep.

4. Sucked your soul through pee-pee hole.

5. Head Candy.

6. Curled your toes then and your toe nails fell off.
7. Oral sex so good, you flashed back and jerked of to the memory of it later on that day.

That girl with the eye patch gave me ridiculous head last night. Some of the best i've ever had, Sweet Brains...

brain leakage

When you have just thought of something completely random and off-topic, and decide to write/draw about that completely random topic.

Man 1: "Hey d00d. Look what I just drew."
Man 1: *shows picture of EPYC Randomness.
Man 2: d00d, that is just pure brain leakage man.
Man 1: I know, right?.

dunder brain

A better, more correct version of 'dunda head.' Dunder brain can be used as a friendly insult, but do not try actually paying somebody out with this word, because you will seem like a complete moron, and a 'dunder brain' yourself.

Can refer to someone who is muddled in the brain, or a generally silly person.

Kayla: "You're a dunda head"
Me: "No, Kayla, it's dunder brain"
Kayla: "You're a retard"
