The Jargon File (version 4.4.7, 29 Dec 2003):

trampoline
 n.

    An incredibly hairy technique, found in some HLL and program-overlay
    implementations (e.g., on the Macintosh), that involves on-the-fly
    generation of small executable (and, likely as not, self-modifying) code
    objects to do indirection between code sections. Under BSD and possibly in
    other Unixes, trampoline code is used to transfer control from the kernel
    back to user mode when a signal (which has had a handler installed) is sent
    to a process. These pieces of live data are called trampolines.
    Trampolines are notoriously difficult to understand in action; in fact, it
    is said by those who use this term that the trampoline that doesn't bend
    your brain is not the true trampoline. See also snap.
