Cruise Line 

To "Cruise Line" is the act of pushing one's face in between two LARGE breasts, and rocking one's head from side to side very rapidly while making a vigorous, lip-vibrating "brrr" sound and in the process adding more power and more brr to the vibration due to the larger breast. It is recommend to use the "cruise line" on a girl with larger than a D-cup. Very close to motorboating just has to increase the scale of power.

"Did you see her rack, I just want to cruise line those puppies"

Dominican cruise liner

A vessel or vehicle used to smuggle in immigrants into the United States. A boat could be used by hiding in a container box for the journey. Or a truckload of bananas is another example as one may height crossing the Mexican border to make it to the promised land. Where the promise of welfare programs, and Pres. Obama sponsored free phones awaits usually the bottom of the barrel of citizens.

Jose made it in on a Dominican cruise liner.

The drug cartel sponsored the Dominican cruise liner in hopes of getting new product to the states.

That line has already been cruised 

An alternate way of saying that line has already been crossed; saying that the boundaries set by oneself or someone else have been violated in the past in some manner.

“Listen, I’ll stop being annoying to my brother, I promise!” “That line has already been cruised young man!”

cruiselined 

While motor boating a woman with large tiddies, she pulls them apart as far as she can then, slams them into your skull.
Similar to two cruise ships sandwiching a smaller tuggy boat.

Bruh, was motorboating Angela White and she cruiselined me so hard that I got a legit concussion.
