MDA 

Common nomenclature for 3,4-Methylenedioxy-Amphetamine. Related to MDMA (Ecstasy) but different, at least effects-wise. Basically it's like rolling but much less tactile (usually no full body orgasms like X), and less empathetic and lovey-dovey. On the other hand, it gives a powerful feeling of euphoria and bliss, gives you some crazy visuals, and enhances music to an INSANE degree. The music enhancement is the reason that some DJs prefer it to MDMA. Most often found in commercial ecstasy pills, passed off as MDMA. Occasionally some lone-wolf chemist will make a bunch for themselves and their friends.

MDA, I can see the music.

MDA 

Myspace display of affection. When one flaunts their lover all over their myspace. The word usually denotes clinginess (as does PDA). Signs that you have too much MDA:
1.) Your headline has their name and/or date.
2.) You have one or more pictures of just them, from his/her myspace, not taken with/by you.
3.) You say something universal and cliche like "I love him so much, he's my world, he's always there for me, I can't live without him.
4.) You have more pictures of you too than pictures of just you or you with other friends.

Me: Holy crap, they've only been dating for 3 hours and Brad's number 1 on Sam's top 8, even before Sam's sister Beth!
Random bystander: Definitely a case of MDA.

mda stalker 

I gun nut who stalks the Facebook pages of the local Moms Demand Action group and follows them to where they are having lunch. Sometimes by himself or if time permits, he will organize friends to join him. This stalker also practices open carry and comes armed with a gun claiming he is defending his 2nd amendment rights. The sad reality is, he's a stalker who is trying to intimidate.

Ex: Kory checked his local MDA Facebook page everyday until finally one mentioned meeting for lunch the next week. Quickly, he sent out the alarm to the other MDA stalkers to unite!
