What is the meaning of "the lamest"?
Answer from a Native speaker
"Lame" is an adjective used to describe something that is not cool, fun, or hip. Here, the speaker is saying that the bears are the "lamest" to label them as uncool for not having interesting TV channels to watch. He has used the "-est" ending at the end of the adjective to emphasize the "lame-ness" of the bears. Ex: This class is the lamest. We just watch slides all day and the teacher doesn't even teach. Ex: This party is lame. Let's bounce (leave).
