An acronym that stands for Big Hairy Dick. Typically refers to any male genitalia that is large and covered in hair.

The colloquial definition of this term plays on its similar sounding and spelling to the word Ph.D. Thus, BHD is often written as Bh.D., giving the word a revered connotation that is directed towards whoever is the respective Bh.D. holder.

Similar to phd: Pretty Huge Dick
Girl #1: He was huge! No joke, I almost gasped when I saw his member.
Girl #2: Was it a...? You know, a...?
Girl #1: You mean, a...? Mhm, it was ;-)
Girl #2: I am so jealous! God damn, I wish my boyfriend had a BHD!

(Used as a pick up line/a means of impressing someone)
Guy: I attend college at (insert any prestigious Ivy League university here). And, I also have a Bh.D.
Girl: You mean, a Ph.D? Well, wow! Good for you! Was that hard?
Guy: No, baby a Bh.D. A big hairy dick. And yes, it is often hard... Very hard.
Girl: *Stunned*

(Ironic Usage)
Guy #1: So, Ashley's pretty hot.. Did you see her tonight?
Guy #2: Yeah she looked good, but I don't know man, I hear she has a Bh.D.
Guy #1: Really? Ah, FUCK! She really fooled me. Goddamn trannie!
Guy #1: I feel you. All the good ones are hot until you meet them, get them in bed, and find out they have a Bh.D. in Anatomy. It fucking blows.

n. Stands for Broken-Heart Disease. Normally suffered by people who are separated from that 'special someone' for a prolonged period of time for whatever reason (i.e. break-up, vacation, moving, etc.). Symptoms include crying, loss of appetite, thoughts of the world being over, depression, and more crying.
Guy 1: Dude, what's wrong? You haven't been talking much today.
Guy 2: Oh, *insert current love interest's name here* left for the summer so I won't see her for the next 6 weeks. So you could say I'm experiencing the first stages of BHD.
Guy 1: .......fag.
