what? the kiss. Congo's french.
although it quite funny how non physically affectionate most males are as compared to the Europeans. most european countries accepts men kissing on the chicks as a normally sign of kinsmanship.
i see that the english, the americans and asians are somewhat standoffish when it comes to this form of male interaction.
but looking solely at the gifs, it looks like Kongo is have a bit of silly fun whereas Rampage is being a bully trying to take the mickey out of Ariel. putting one's hand around another person's throat is an aggressive action in my book.
