When telling a story, one uses this phrase to leave out all the intricate details of the situation, leaving all the details up to the one listening. Mainly used when bragging to one's friends about one's sexual prowess. See, "yadda yadda yadda".
I was delivering pizza last night, and when I rang the door bell, she opened up the door wearing nothing but a towel, and one thing lead to another - and now I gotta take a pill to "supress" this damn thing.

The obvious definition is that you did one thing, which led to a situation where it was logical to do some other related thing.

It can often be used to say something without actually saying it--you might say the phrase to imply that something happened which you are not going to be explicitly explain... (see the example below.)
I heard this rumour about John and Beth: Beth invited John to dinner last week, during which he accidentally spilled wine on his pants. Beth told him he better take them off so she could clean off the wine before it made a permanent stain. I guess John got a little aroused by the situation, and one thing led to another...

Conversation glosser-over.

See also; yada yada

Mostly used as a substitue to sexual descriptions, it can also serve to shorten or skip over parts of conversations. It allows the listener to fill in the blanks themselves with their imagination.

The phrase was used recently as a lyric in an Urban Hip-Hop Song; "Holidae In".

"Well, me and my girlfriend were watching a movie, and..... one thing led to another and now I've got child support for triplets"
