the term used in the gay community for the presumed tendency lesbians have of quickly moving together after dating for a short period of time. See U-haul lesbian.
Although not unique to lesbian couples, this behavior is stereotypically attributed to lesbians.
The comedian Lea DeLaria joked:

Q: What does a lesbian bring on the second date?

A: A U-haul.
The U-haul joke symbolizes the lesbian urge to merge.

Get the urge to merge mug.
When entering a highway or freeway, when you don't merge from the entrance ramp to the road itself until the entrance lane ends, and just expect that Moses will part the traffic for you so you don't end up smashed between a semi and one of those fat-ass Hummers. So named because the sheeple in California, too oblivious to reality to actually take the initiative and merge when there's an opening *before* the lane ends, are particuarly fond of this traffic maneuver.
"Look at me, I'm following the solid white line onto the highway because I suck at life."

On a two lane limited-access freeway the "merge of shame" is where you are in the far left lane against the wall while a vehicle tailgates you. The car behind you accelerates to illegaly pass you on the right, changes lanes without signaling but before they pass and cut you off they are forced to get back behind you due to a SLOWER moving car in the right lane.
That bitch behind me in the SUV on her cell phone just had to take the merge of shame!!
