lufsig 

The plush toy IKEA manufactured in 2013. The toy became an anti-government symbol in Hong Kong starting from November 2013, as the toy resembles Leung Chun-Ying, the then-Chief Executive of Hong Kong.
The toy is renamed as "Wolf" on November 2014.

I threw a Lufsig to 689 (CY Leung) out of my anger and I was escorted out by the security men afterwards.

lusignan 

A substitute for the name lasagna. often a last name for brunette girls that go through phases for things like mushrooms, frogs, avocados, and even llamas. It is very hard to pronounce (loo-sig-nan).

Iċ lufiġe þe 

“I love you” in Old English, pronounced roughly as “ich looviyuh thay”. Can easily be passed off as gibberish if you want to confess to someone without them realizing, or can be extra sweet if you say it to someone who understands Old English.

Person 1: “Iċ lufiġe þe”

Person 2: *blushes* “Iċ eac lufiġe þe” (“I love you too”)
