tcmalloc is a memory allocator that's optimized for high concurrency situations. The tc in tcmalloc stands for thread cache — the mechanism through which this particular allocator is able to satisfy certain (often most) allocations locklessly. It's probably the most well-conceived piece of software I've ever had the pleasure of reading, and although I can't realistically cover every detail, I'll do my best to go over the important points.
