Forced Interlace
When you're walking alongside a date, and, without your consent, they hold your hand with the fingers interlaced with one another as a gesture to claim you as theirs. A public display of "I'm in a relationship with this person." Especially relevant when you are in the early stages of dating, and one party isn't sure how they feel about the other, so it's incredibly uncomfortable and awkward.
"How was your date last night?" "It was alright, but she totally did a Forced Interlace on me! I tried to block her and tighten my hand up, but she was relentless... so we held hands the rest of the way to the train. Gah!"
