It's usually used without much distinction from the one-hump camel (🐪). However, because the two humps make it look like it's carrying a heavier load, it's sometimes used humorously to emphasize a very difficult situation.

This two-hump camel is called a Bactrian camel and is better adapted to harsh environments than the dromedary. Therefore, it can be used to symbolize not just a tough situation, but immense patience or perseverance. The two humps can also give a sense of stability, so it's sometimes used as a metaphor for situations where balance is important.
