Standing for "Deep and Meaningful" standing for when two (or more) friends are at a pub, club or party aside from other friends talking privately about something major (or seemingly Major). It can be a couple in a relationship talk but can just as likely be friends talking about earlier events or comments that have affected them, and wish to discuss in private without leaving the pub/party/club/etc.

With Circles of friends, when they are in a D+M it is advised to steer clear of them until it is finished unless you are definitely sure you're sure of the topic and it geneuinely relates to you.

If unsure ALWAYS check with someone else within the group of friends, who is NOT participating in the D+M to check whether it is ok to approach them and talk.

Don't @ me. Usually used when you say something commonly disagreed with that you won't change your opinion on, or don't want to hear other peoples' opinion on. Often used as a joke or with an obviously exaggerated/satirical opinion.

The act of docking AND munting.

Docking is placing the head of your penis into the foreskin of another man's penis. Munting is find a dead body and having someone (or more than one person) stands on top of it, squishing and forcing out the guts and insides, while the other person goes down on it and slurps up what comes out.
"Last weekend, me and a couple of friends did D&M. We did some docking and munting."
