The "two-backed beast" is a euphamism for having sex. For some reason, people can't just say "having sex," they have to come up with a clever way to say it.
"Last night I was making the two-backed beast with my boyfriend"

Bumping uglies, knocking boots, burying the salami, etc

Get the Two-Backed Beast mug.
It is a popular lyric to a song, but sometime used i phrases or as comparisons to things. it's basically taking one step back. and it means, making progress towards something but making less progress rather than more, if that makes sense.
"one step forward < two steps back"
I was trying to finish my math homework, and i did the beginning, but going to that party before finishing was one step forward and two steps back.
